Keynote: Affairs don’t just happen: Protect, repair and recover
Time : 10:00 AM-10:45 AM
Biography:
Lissy Ann Puno has extensive experience practicing in the region as a Counseling Psychologist. She is the co-founder of the International Counseling and Psychology Centre in Singapore. She offers counseling and psychotherapy across the developmental stages as well as gives talks, trainings and workshops covering a variety of relevant topics promoting psychological wellness. In 2016, she released her first book entitled “Affairs Don’t Just Happen” which focuses on how to protect, repair and recover your relationship from infidelity.
Abstract:
Relationships and marriages have increasingly been faced with challenges of boredom, disillusionment and infidelity. Couples are finding themselves faced with the threat of ending the relationship sooner and find themselves at a loss on how to strengthen their relationships. Extra relational and extra marital affairs have been increasingly on the rise. Why has it gotten out of control? When is it out of control? An understanding of the stages of the love relationship is crucial. The theory of how the unconscious pull of attraction can eventually lead to disillusionment that creates vulnerability towards infidelity. What creates the attraction between two people? Why feel a pull towards one versus the other? This period of vulnerability can be setting up the stage for an affair amidst the current trend of relationships being disposable and replaceable. Patterns of behavior amidst emotional turmoil will be identified as one may find themselves trapped in the web of intrigues, deception, shame and betrayal that comes with affair discovery. The pain, hopelessness and helplessness during this time may also lead to ineffective behavior. Discover ways to nurture a relationship back into trust, safety and commitment through effective relational skills versus destructive and ineffective coping actions The 8 C’s towards a mature and healthy relationship will be highlighted. What type of support do couples need at this time to maintain a connected relationship through a longer life span? The role of a couple’s therapist is challenged and expanded as the relationship becomes the client and not the two individuals existing in two different worlds. Current trends in dialogue and communication skills will be introduced.

Keynote: Imaging in post treatment glioma: The concepts of pseudo progression & pseudo response
Time : 10:45 AM-11:30 AM
Biography:
Consultant Radiologist in MRI department Nanavati Superspeciality Hospital, Mumbai.

Abstract:
Glioblastoma multiforme is one of the commonly seen primary malignant brain neoplasm in adults. The current standard of management is surgical resection followed by radiation therapy and adjuvant Temozolomide chemotherapy. This approach has been proven to improve the overall post treatment survival. In addition, in 2009, bevacizumab for recommended for recurrent glioblastoma. With the change in treatment regime there has been introduction of a new concept of Pseudo-progression and Pseudo-response.
These treatment regimens have effect on the MRI appearance of the brain parenchymal disease morphology. Earlier the disease extent and grading was based mainly on the degree of enhancement, which in turn is based on disruption of blood brain barrier. Now we understand that its neoangiogenesis rather than disruption of blood brain barrier which correlates with tumor grade. This forms the basis of MRI perfusion technique.
Pseudo progression is widely believed to be more frequent following concomitant RT-TMZ. By definition, pseudo progression subsides without further treatment but, in some cases, appears to progress with time into radiation necrosis or treatment related necrosis.
The diagnosis of pseudo progression is critical in the treatment protocol as, it may influence the clinical recommendation to continue with adjuvant chemotherapy rather than change to a second-line therapy.
Antiangiogenic agents such as Bevacizumab, an anti-VEGF antibody may produce a rapid decrease in contrast enhancement with a high response rate and 6-month progression-free survival, but with rather modest effects on overall survival.
The advanced imaging techniques like arterial spin labeling, dynamic susceptibility contrast perfusion imaging as well as spectroscopy help in differentiating these treatments induced changes from residual / recurrent tumor and thereby guide treatment protocol. A thorough knowledge of these entities and their imaging morphology with advanced MRI sequences is of utmost importance.

Suchi Deshpande
Doctor
Keynote: Adopting laughter therapy to get dosage of happy hormones
Time : 11:50 AM-12:50 PM
Biography:
M S Suchi is an experienced International Pre School Principal/Manager who learnt laughter exercises from many coaches around the world. She then designed laughter therapy which is being used in many places such as hospitals and senior activity centers. She provides individual and group therapy as well in educational and home settings. She now engages in building social awareness about depression and anxiety and the harm it brings to people, families and communities. Her aim is to encourage people to seek help early and get on the path to recovery.
Abstract:
There is a lack of awareness about what happy hormones are and what can be done to get them. People tend to feel unhappy for multiple reasons and sort towards addiction and alcoholism and commit suicides in some cases. Review of books and research shows that feeling good and taking care of our emotional well-being will resolve the problems of addiction, alcoholism and it will decrease suicide rates as well. Adopting laughter therapy and getting hormones which makes one feel good will help many to recover from depression and anxiety thus reducing suicidal rates. One needs to work on his/her energies using laughter therapy which is a positive approach for not having depression and anxiety or use it as a holistic way to recovery. The laughter therapy which includes ways to get the dosage of happy hormones promotes overcoming depression and anxiety using a fun way. Leading fulfilling lives encourages people to get a new life away from addiction and alcoholism. Repeated sessions must be conducted to remind people that the new life should go beyond just seeking medical and counseling help and also include rebuilding spiritual, physical, emotional, relational and mental health. The model has been put together for testing in many settings including hospitals, elderly homes and senior citizen centers. This is not a research book or paper. It is just an effort to demystify the help available for depression and anxiety. It is an attempt to motivate and encourage people to seek help and take a simple approach to remember and work on all aspects of their recovery.

Abstract:
We entered in a new era of cancer treatment characterized by the arrival of novel therapies. Immunotherapy has revolutionized the management of various solid tumors and hematological malignancies. On the other hand, the emergence of unpredicted multi-systemic side effects resulting from those agents became challenging for clinicians. Neurological toxicity, while rare, could be life threatening and even lethal. In addition, neurological toxicity is certainly under-diagnosed, considering the paucity of current supporting literature. Novel therapies are linked to unprecedented clinical pictures; physicians need to be vigilant. The next step, establishing a plan in the absence of algorithm, relies on judgment and insight. This presentation aims to raise awareness about the emergence of uncommon neurological events, in the new era of immunotherapy. Short cases scenarios will be presented supported by radiology images and pathology pictures. “Quiz” questions will be prepared to interact with the audience. The goal is to trigger interest about the field of Neuro-Oncology. The presentation will be adapted for guests of every level of training (students, PhD, physicians, specialists).

Abstract:
Epidemiological studies have been done from a cross section of adolescents living in rural and urban in-tact families. However, less focus has been given to the psychological well-being and suicidal behaviour of adolescents with early parental separation, traumatic life experiences and living in non-biological homes.
Method: Paper and pencil method assessed socio-demographic, suicide behaviour (SBQ-4) and psychological well-being (WHO-5) among 73 adolescents aged 10 -18 years, living in ten relocated homes, registered with Child Welfare Committee, using purposive sampling, descriptive cross sectional and single-subject design. Managers of two homes refused permission and thirteen schedules were excluded. Leading questions pertaining to early familial life or experiences in present homes were avoided due to the adolescent’s vulnerable situation. Confidentiality assured. Data was analysed using Descriptive statistics, T Test and correlation (SPSS 16), with 95% CI.
Results: Mean age was 13.86 (±1.93) years, more girls in 10-12 years (p<0.001), residing in homes for 7- 10 years (p<0.001). One-fourth of boys were studying in high school and almost a third of girls in middle school. While girls had significantly (p<0.05) higher overall scores on SBQ (5.59 ±2.17), more boys had made/thought about killing themselves (1.51±.91), while significantly more girls (p<0.05) were contemplating suicide (1.39±.65). Significant differences in well-being seen in one in five adolescents (p<0.001), indicating poor well-being and need for further evaluation.
Recommendations and Conclusion: Adolescents will be the productive workforce in the next five to ten years, account for about a third of all suicides in the country and a large majority of these young attempters, have not received any kind of psycho-social interventions. The absence of accurate estimates has resulted in a serious mental health treatment gap among child and adolescents in low and middle income countries. A multi-disciplinary team approach can solve the human-resource gap in healthcare, with psychiatric social workers’ evidence-based services playing a major role in the prevention, management and policy of mental, neurological and substance use disorders, including family and school based identification and preventive interventions.

Abstract:
Statement of the problem : Anti-Ma2 antibody -associated encephalitis, which usually occurs in young men with germ cell tumors of the testis with features of encephalitis ,it can also present in elderly females with basal ganglia disorder features like Parkinsonism and cerebellar ataxia in absence of limbic or brainstem or di encephalic encephalitis . Patients may not present with any form or symptoms of encephalitis but the treatment response rate with steroids , IVIG , plasmapharesis to control the initial symptoms is very high and after resection of the tumor all the symptoms can be totally cured .So ,even there is no evidence of tumor on basic contrast CT /MRI scans ,other special imaging like FDG -PET or highly advanced tumor searching imaging plus serum tumor markers of different tumors should be considered as the tumor spectrum associated with anti ma 2 antibody encephalitis is huge and resection of the tumor can totally cure the patient .
Case: A 68-year-old female presented to our department with resting tremor of right hand for 2 years . After 6 months, resting tremor gradually involved her right leg. Antiparkinsonian drugs were initiated but her symptoms worsened gradually. Since last 3 months, she developed features of imbalance with occasional falls and a weight loss of 10 kg.Neurological examinations showed features of Parkinsonism. Brisk DTR right side more than left with abnormal cerebellar signs.
CE MRI mild atrophy of cerebellum. Anti-Ma2 antibodies in serum and CSF positive .Serum cancer antigen 72-4 was elevated. A sigmoid colon mass was discovered by colonofiberoscopy and adenocarcinoma was diagnosed via tissue biopsy. Steroids, IVIG and resection of the tumor completely cured the disease.
Conclusion: 1) Parkinsonism or cerebellar ataxia as main component of anti-Ma2-associated encephalitis was rarely reported.

Satu Pihlaja is currently a PhD student at the University of Helsinki, Finland. She studies internet interventions for mental health with a research group in the University Hospital of Helsinki and Uusimaa. She has published a review paper on therapeutic alliance in internet interventions.
Abstract:
The efficacy of human supported internet-delivered asynchronous self-help Cognitive-Behavioral Therapy (iCBT) for depression is well established. Studies suggest that guidance is important and that programs without therapist support are less effective. Different ways of support have been studied. The objective of this study was to find out if an Intensive Telephone Support (ITS) can increase the proportion of patients completing the program (primary outcome), to prevent unnecessary delays during the treatment and to improve the effects of iCBT on symptoms of depression. Patients on iCBT who expressed sub-optimal motivation (n=100) have been randomly assigned to either Intensive Telephone Support (ITS) added to iCBT or to iCBT as usual (seven sessions of standard CBT on the internet, with written asynchronous therapist-patient communication). There were significantly more program completers in the ITS group than in control group. Predictors and mediators of these effects, as well as monetary rationale for ITS will be discussed.

Abstract:
With ongoing advances, neuro-imaging has moved much beyond morphology. Now we can provide functional and physiologic information through non-invasive imaging techniques as well help the surgeon in pre-operative planning as well as disease follow up. Arterial spin labeling is a novel, completely non-invasive, non-contrast MRI perfusion technique which can predict areas of neo-angiogenesis and help grade the tumor. Various studies have proven its comparable sensitivity and specificity to routine dynamic susceptibility contrast perfusion. Diffusion tensor imaging ascertains if the white matter tracts are destroyed, infiltrated or displaced by the tumor as well as guides the surgeon to plan surgical trajectory. With functional MRI, areas of activation for key task like motor activity, sensation, speech could be delineated, again helping in surgical planning and in improving patient outcome. By providing high resolution 3D data set for neuro navigation the surgical entry point could be made more precise decreasing the craniotomy size. Along with T1, T2, diffusion, susceptibility weighted images, arterial spin labeling, diffusion tensor imaging, MR spectroscopy, DSC perfusion, functional MRI and neuro-navigation are a part of the brain tumor imaging protocol at our institute, especially in cases with a surgical plan of management. The aim of this presentation is to highlight the role and utility of these MRI imaging techniques in brain tumor imaging.

Abstract:
Studies of brain connectivity alterations using resting-state functional magnetic resonance imaging (rsfMRI), diffusion tensor imaging (DTI), and, more recently diffusion spectroscopic imaging (DSI) data have advanced and enlarged our knowledge on the organization of large-scale structural and functional brain networks, which consist of spatially distributed, but functionally linked regions that continuously share information.
Brain's energy is largely consumed at rest during spontaneous neuronal activity (~20%), while task-related increases in metabolism energy are minor (<5%). Spontaneous ultralow-frequency fluctuations in BOLD-based rsfMRI signals (<0.01Hz) at the level of large-scale neural systems are not noise, but orderly and organized in a series of functional networks that permanently maintain a high level of temporal coherence among brain areas that are structurally segregated and functionally linked in resting state networks (RSNs). Some RSNs are functionally organized as dynamically competing systems both at rest and while performing various tasks.
The default mode network (DMN), the most important RSN, is even more active during rest and involved in realization of tasks like memory retrieval, emotional process, and social cognition.
Cortical connectivity at rest is reportedly altered in several neurological and psychiatric disorders. Most recently, human brain function has been imaged in fMRI, and thereby accessing both sides of the mind-brain interface (subjective experience and objective observations) has simultaneously been performed. As such, functional neuroimaging moves onto new potential applications like reading the brain states, discriminate neurological dysfunctions (if any), brain- computer interfaces, lie detection, and alike.
The contribution aims to review and evaluate the most current approaches for early detection and classification of cognitive impairments and dementia, particularly among syndromes with relatively similar behavioral effects, based on alterations in brain connectivity at rest explored by rsfMRI, DTI, and DSI.

Title: Many faces of DCTN-1 (Dynactin) gene mutation in neurodegenerative diseases
Biography:
Rajib Dutta is a Postgraduate Neurology Trainee in China with MRCP UK London, has completed his Diploma in Emergency Medicine and Critical Care (Royal College UK), Diploma in Clinical Neuropsychology (UK), Pediatric Neurology certification BPNA (UK, ongoing).
Abstract:
Axonal transport machinery is central to neuronal health and survival, with dysfunction implicated in several neurodegenerative disorders including AD, FTLD, MND/ALS and PD and PD plus syndromes, HMN 7B and Perry Syndrome all associated with dynactin pathology. A 45 year old working lady presented to us with bradykinesia for six months, accompanied with difficulty in walking for four months. Six months ago, the patient started feeling clumsy while doing house hold work and her movements became slower as time passed by. Four months ago, she started to have difficulty in walking which gradually aggravated. Since onset, she was depressed and experienced sleep related behavioral issues but never lost weight. Her mother had similar symptoms but was on anti-parkinsonian drugs. P/E: increased muscle tone in all 4 limbs, right>>left with reduced right arm swing, with masked type faces. In view of positive family history, parkinsonism symptoms, depression/apathy patient was diagnosed with definite PS (Perry Syndrome) supported by international diagnostic criteria. To confirm PSG showed airflow restriction and hypoventilation using apnea hypopnea index with no respiratory acidosis in ABG. Genetic test was performed which confirmed novel point DCTN 1 gene mutation. Patient was started on anti-parkinsonian agents, anti-depressants and clonazepam and her symptoms got somewhat better. We have diagnosed the first Asian case of a PS with a novel point mutation p.G67S of DCTN1 gene in exon 2 not reported in literature yet. Our observation suggests that patients/family members may not present with all the cardinal features of PS but still it has to be ruled out with gene testing mainly because of two reasons: (1) Early timed diagnosis will lead to early symptomatic treatment which can significantly modify the progression of disease and (2) improve quality of life by use of diaphragmatic pacing and can prevent life-threatening episodes of acute respiratory failure and eventually death.

Abstract:
In medicine, we are trained to consider a common denominator in a unicist scenario to account for several concomitant symptoms, especially in young patients. Patients diagnosed with either neurologic or oncologic conditions are prone to various comorbidities resulting from their initial diagnosis. Even in the case of young adults, we need to investigate a broader range of possibilities. We present the case of a young man in his early 30s, diagnosed and treated several years prior for a low-grade glioma (primary brain tumor), consulting for seizure recurrence. The main Ambition of seizures initially when his oligodendroglioma was first diagnosed however the tumor is stable on imaging for several years. Three different seizure types are documented in detail. Even if the presence of a low-grade glioma could explain by itself the seizure recurrence, the thorough symptom description and evolution lead to a different hypothesis. This case emphasizes the importance of a good clinical history and research of pertinent details in neuro-oncology patients to reach a prompt and accurate diagnosis. This case describes how three independent “seizure types” surprisingly occurred in a single patient. We threw light on three concomitant etiologies: Glioma-related seizures, pseudo-seizures and metabolic tonico-clonic generalized seizures resulting from a malignant insulinoma. The goal of this presentation is to trigger interest about the field of neuro-oncology. The patient described signed a written consent, confirming his agreement to have his history presented for academic/teaching purpose.

Abstract:
On June 14, 2017, at approximately 3:51 am, I was found unresponsive, while seated in the driver's seat of my unmarked FWPD vehicle. The responding Officer knocked on the window of the car until I woke up and rolled the window down. I told the Officer that was heading to KREAGER PARK, and I was immediately asked by the Officer; this was the revolver, I intended to use to end my life. I was asked if I had been drinking, I responded yes, and that I had a half glass of vodka to accelerate the effects of the painkillers/muscle relaxers I had taken to assist with my death. I admitted the consumption of several prescription pills and repletely stated that I wanted to end my life. Now, if you ask yourself; rather than obtaining me the medical attention needed. Former Indiana Governor Mike Pence, signed a law in 2015 requiring the Indiana Law Enforcement Academy to instruct trainees regarding CIT protocol.

Abstract:
Dysexecutive syndrome (DES) is defined as an impairment of executive functions constituting of two domains: behavioral dysexecutive syndrome (BDES) and cognitive dysexcutive syndrome (CDES) which are not accompanied always[1]. A growing body of studies demonstrated that BDES is a common post-stroke neuropsychiatric comorbidity. The prevalence of BDES in stroke survivors varies ranging from 3% to 25% possibly attributed to the lack of standardized diagnosis methods and variances in study sample and study mode.
Post-stroke BDES comprises varieties of clinical presentations, the most prevalent of which are anosognosia and hypoactivity with apathy-abulia[2]. The clinical course of BDES in stroke population has not yet fully elucidated. Some studies showed that there was only a minor decrease of prevalence of BDES several month after stroke , suggesting the possible chronicity of BDES. Possible clinical correlates of behavioral symptoms in stroke are global cognitive impairment, executive dysfunction, premorbid personality and psychopathology and stroke severity. Despite BDES is also a possible predictor of poor post-stroke physical function and can increase the burden of caregivers, it is still often underestimated and untreated. Furthermore, the treating methods for BDES are limited and lack of high quality supporting evidences. Some studies suggested that antipsychotic drugs might be effective in controlling behavioral dysexecutive problems such as agitation, apathy and disinhibition. The methods of psychosocial treatments varies including caregiver education, aromatherapy,exercise and behavioral intervention whereas their effectiveness is still under debated.
The neuroanatomical pattern of post-stroke BDES is rarely studied. Lesion studies demonstrated that disruption to frontal-subcortical circuit (FSC) is the pivotal cause of BDES[3]. First of all, frontal lobe is treated as the key component of FSC. Frontal lesion and reduced frontal volume contribute to behavioral disturbances. Particularly, abnormalities of orbitofrontal cortex (OFC) and medial prefrontal cortex (MPC) involving the reward representation, response selection and behavioral flexibility are closely correlated with apathy, disinhibition and other dysexecutive syndromes in patients with neurologic diseases. Further, Basal ganglia are involved in motivated behavior, behavioral switching theory of mind. Basal ganglia lesions can lead to apathy ,abulia ,disinhibition , irritability and labile behavior. An abrupt of BDES can be observed in those thalamic stroke patients with
complex syndromes varying according to the nuclei affected. However, very few structural brain imaging studies have been published on BDES or behavioral symptoms in stroke. The existing studies found associations between BDES/behavioral symptoms and infarcts in the right hemisphere,anterior capsule , thalamus, and WMH. These studies have many limitations such as small sample size, biased sampling, lack of standardized assessment of BDES and rude classifications of lesion location. Therefore, the studies of high quality with a more advanced method to investigate neuroanatomical lesion pattern are keenly demanded.
Except for the neuroanatomical abnormalities, cerebral hemodynamics and metabolism are also suggested as the possible mechanisms of BDES after stroke. There are a great deal of evidences supporting the role of reduced cerebral blood flow (CBF) in CDES whereas limited studies reporting the relationship of CBF and BDES. Subjects with reduced CBF in frontal lobe presented a worse behavioral executive function. On the other hand, an improvement of executive function was observed when CBF was augmented, which possibly implicated that augmentation of focal CBF could be a promising treating method of BDES. Meanwhile, several studies showed that dysexecutive function was associated with lower metabolic level in frontal lobe. Further investigations on role of CBF and cerebral metabolism in BDES in stroke population are suggested to apply.
To conclude, the existing literatures on BDES and stroke suggest that BDES is one of the most common post-stroke psychiatric comorbidity and a combined neuroanatomical and neurobiological lesion accounted to stroke substantially serves as the underlying mechanisms of post-stroke BDES. Standardized diagnosis criteria and a deeper understanding of the mechanism of post-stroke BDES is urgently needed , which may benefit to recognize BDES in stroke survivors as early as possible and select the appropriate treatment, therefore, result in a better outcome of stroke.
