Bilateral thalamic infarct (BTI) represents an uncommon stroke presentation. Pathophysiology recognizes the occlusion of an anatomic variant of the thalamic blood supply from perforating branches of posterior cerebral arteries. Presentation could be nonspecific and dramatic in the same time, being coma or stupor the possible clinical scenario encountered. Diagnosis is performed by neuroradiological imaging showing the typical bilateral paramedian thalamic infarcts. Literature lacks of evidence in very old patients, therefore we describe two cases of BTI occurred in octogenarians presenting unresponsive. BTI in very old patients presenting comatose should be taken in account as diagnostic possibility.

In 1880 French neurologist Jules Cotard described a condition characterized by delusion of negation (nihilistic delusion) in a melancholia context. Recently, there has been a resurgence of interest in Cotard’s syndrome. The most prominent symptoms of Cotard’s Syndrome are depressive mood, nihilistic delusions concerning one’s own body and one’s own existence, delusions of guilt, immortality and hypochondria. The aim of the present paper is to review literature evidences concerning Cotard’s syndrome and to describe a clinical case keeping in the background the recent trends on its psychopathological implications. In the clinical study, the following sequence of stages emerged: the dissociative side, expressed as a loss of body-mind cohesion; the ‘mixed’ mood disorder, with depressive-manic episodes, and a persecutory background, all coexisting in the anguish of the idea of a body falling apart, the anguish of a descent towards the abyss of melancholia and/or an ascent to unlimited euphoria, characteristic of an “uncommon alarm” for loss of Self cohesion.

MicroRNA Let-7f Mediates Mitochondrial Respiratory Deficit Induced by Repeated Ethanol Exposure and Withdrawal in HT22 Cells

Marianna E. Jung, Daniel B. Metzger

International Neuropsychiatric Disease Journal, Page 303-315
DOI: 10.9734/INDJ/2014/11533

Aims: The expression of gene and gene product is typically inhibited by a small non-coding RNA (microRNA) or DNA methylation. The aim of this study is to investigate mechanisms involving microRNA let-7f by which the repeated cycles of ethanol exposure and withdrawal provoke mitochondrial respiratory damage.

Study Design: The rat or cell model of repeated withdrawal from a high dose of ethanol exposure was used to mimic human alcoholics who repeat the cycles of heavy drinking and unsuccessful attempts at abstaining. 

Place and Duration of Study: Department of Pharmacology and Neuroscience University of North Texas Health Science Center at Fort Worth, between June 2011 and March 2014.

Methodology: Male adult rats received an ethanol program, consisting of two cycles of ethanol exposure (4 weeks) and withdrawal (2 weeks). At the end of the ethanol program, one hemisphere of each rat was used to measure the level of let-7f using TaqMan let-7f primers and qPCR. The other hemisphere was used to measure the methylation of cytosine in let-7f gene using bisulfite conversion and pyrosequencing.  Separately, HT22 cells (mouse hippocampal cells) were exposed to an ethanol program, consisting of two cycles of ethanol exposure (20 hours) and withdrawal (4 hours).  During the entire ethanol program, the cells were treated with let-7f antagomir (inhibitor) or a methylation-inducing methyl-donor. The role of let-7f in mitochondria was assessed by quantifying a mitochondrial enzyme, cytochrome c oxidase-IV (COX subunit IV) and real-time mitochondrial respiration using an immunoblot method and XF respirometry, respectively.

Results: The level of let-7f increased (2.4±0.5 fold increase), whereas the methylation of let-7f gene decreased in the brain of rats that underwent repeated ethanol exposure and withdrawal (called “repeated-ethanol/withdrawal”). The methyl-donor treatment completely abolished the increase in let-7f induced by repeated-ethanol/withdrawal. let-7f antagomir treatment also abolished the inhibiting effect of repeated-ethanol/withdrawal on COX-IV and mitochondrial respiration.

Conclusion: These data suggest that repeated-ethanol/withdrawal provokes the dysregulation of let-7f, thereby damaging brain mitochondria. Mitochondria-associated microRNA may be a potential research and drug target to manage alcoholism.

Jaspinder Kaur, Mandeep Kaur

International Neuropsychiatric Disease Journal, Page 244-254
DOI: 10.9734/INDJ/2014/10848

Aim: Insomnia is subjective perception of dissatisfaction with sleep quality and/or duration. The present study aimed to determine the effects of sleep deprivation on cardiovascular risk factors and health.

Design, Place and Duration of Study: A cross-sectional study was conducted at Exservicemen Contributory Health Scheme (ECHS) Polyclinic, Sultanpur Lodhi, Kapurthala, Punjab, India from July, 2013 to Nov, 2013.

Methodology: All the retired defence personnel and their family members (N=351) were assessed to study physical activity, body mass index (BMI), dietary habits, alcohol, hypertension, hyperglycemia, hyperlipidemia, stress, age, gender, employment, and education as determinants of sleep deprivation. The results were analyzed by Chi Square test with statistically significance of P value<.05.

Results: The total prevalence of insomnia was 27.64% with higher frequency in females (52.57%) than males (47.42%). The prevalence increased with advancing age >50 years (81.43%), unemployment (75.25%), illiteracy (69.06%) and upper socioeconomic status (39.17%). A significant association of insomnia with hypertension (59.80%; P<.05) and stress (28.86%; P<.001) was found. Alcohol (24.40%) and active lifestyle (38.58%) had shown protective role in sleep adequacy. However, sleep deprivation had no significant relation with obesity, metabolic syndrome, dietary practices, blood glucose, and lipids levels.

Conclusion: Insomnia and its significant relation with hypertension and stress increases cardiovascular risk which requires appropriate interventions by identifying those at the risk of chronic insomnia and its associations with females, advancing age, physical inactivity, low education level and unemployment.

DOI: 10.9734/INDJ/2014/10610

Aim: Intellectual disability often referred to as a mental, cognitive or mental retardation is a lifelong condition that affects intellectual functioning and adaptive behaviors. Information about children with intellectual disability attending regular schools is limited in India as there are no mandatory screening procedures used to detect these children while starting their schooling. Hence the purpose of the study was to examine the demographic and clinical features of children in regular schools with intellectual disability and also to explore their parental demographic and clinical features.  

Study Design:  Cross sectional study

Sample: The sample (N=382) was collected from regular school going children within the age range of 5 to 16 years who were referred by special educators.  

Methodology: Clinical diagnosis and psychological assessments were conducted individually for 382 children and their parents.  

Results: Results of the clinical evaluation and assessment indicate that intellectual disability was associated with male gender (61.3%), poor socio-economic status (78.8%), pre-natal, peri-natal and post-natal complications (74%), family history of intellectual disability (11.2%), mental illness (22.2%) and increased maternal age. High rates of comorbidity with psychiatric disorders (48.17%), especially with externalizing disorders were noticed. 

Conclusion: Intellectual disability is associated with psychosocial adversities and psychiatric comorbidities.

International Neuropsychiatric Disease Journal, Page 316-327
DOI: 10.9734/INDJ/2014/10791

Aims: Relative to studies of lived experiences of people with mental health disorders in developed countries, no research has focused on the lived experiences of persons living with mental health disorders in the Niger Delta region and Nigeria in general. Mental health services are not provided at the primary health care level, and only one state hospital provides these services for Rivers State and the surrounding four states. The current understanding of the phenomenology of employment and wellbeing is almost entirely based on studies carried out in developed countries. This study sought to explore the lived experiences of persons with mental health disorders in a public sector employment, to better understand their lived experiences of being employed and to acquire knowledge in an effort to develop supportive programmes for individuals to achieve positive working outcomes.

Methodology: Six people working in the public sector who attended an outpatient clinic of the only regional mental health service were interviewed using a qualitative descriptive-phenomenological design.

Results: Participants reported that work boosts their self worth, information about the disorders and educational supports received from mental health professionals contribute to an improved health and enhance job performance and the value of spiritual support but identified a range of challenges.

Conclusion: Implications for policy are discussed.

Giovanni Abbate-Daga, Enrica Marzola, Federico Amianto, Maurizio Zibetti, Aristide Merola, Michele Lanotte, Leonardo Lopiano, Secondo Fassino

International Neuropsychiatric Disease Journal, Page 356-367
DOI: 10.9734/INDJ/2014/11740

Aims: Certain personality features and psychiatric symptoms are often observed in Parkinson’s Disease (PD) but the effects of deep brain stimulation (DBS) of the subthalamic nucleus (STN) on psychiatric aspects of PD remain largely unclear. We aimed to evaluate changes in personality and psychiatric symptoms before and after STN-DBS in patients affected by PD. Moreover, motor symptoms and L-dopa equivalent daily dose (LEDD) were also investigated.

Methodology: Eighteen PD patients consecutively admitted at the San Giovanni Battista Hospital of the University of Turin to undergo STN-DBS were recruited. Participants were neurologically assessed using the Unified Parkinson’s Disease Rating Scale (UPDRS), and the Hoehn and Yahr scale. They were also psychiatrically evaluated with both      self-report and clinician-rated instruments: Temperament and Character Inventory    (TCI), Beck Depression Inventory (BDI), State-Trait Anxiety Inventory – Y form (STAI-Y), Hamilton Depression Rating Scale (HAM-D), and Hamilton Anxiety Rating Scale (HAM-A).

Results: After STN-DBS, temperament dimensions of the TCI significantly changed whilst character did not. Moreover, both HAM-D and HAM-A improved but BDI and STAI-Y resulted unmodified. We found significant improvements as regards the UPDRS part II and part III scales and L-dopa equivalent daily dose.

Conclusions: The change we found on biological dimensions of temperament after STN-DBS raises the intriguing hypothesis that surgery may entail subtle modifications of personality in PD patients. Further studies are needed to confirm these findings.

Psychological Predictors of Premenstrual Syndrome

Mahbobeh Faramarzi, Farzan Kheirkhah, Sanaz Azadfrouz

International Neuropsychiatric Disease Journal, Page 368-381
DOI: 10.9734/INDJ/2014/12638

Background: Premenstrual syndrome (PMS) is one the most common gynecological conditions that can impact an individual’s interpersonal relationships, social interactions, academic performance, and emotional well-being.

Objective: The aim of this research was to determine the psychological predictors of PMS.

Methods: A cross-sectional study was planned with medical students of Babol University of Medical Sciences. Participants were 350 female students (175 with PMS, 175 without PMS). Psychological risk factors were assessed in four domains: affect, social support, personality, alexithymia with four questionnaires; Depression, Anxiety, Stress (DAS-21); Social Support questionnaire (SSQ); NEO-Five Factor Inventory of Personality (NEO-FFI); and 20-item Toronto Alexithymia Scale (TAS-20). Also, demographic, habits, and gynecological factors were evaluated as non-psychological factors. Analysis of data was performed with χ2 test and multivariate logistic regressions analysis.

Results: The strongest predictor of PMS was alexithymia (OR 4.39; %95 CI 2.62-7.36). Risk of PMS was approximately 2.7 times higher in women with low social support (OR 2.67; %95 CI 1.59-4.48), 1.3 times higher in women with a neurotic character (OR 1.34; %95 CI 1.07-2.31), and 1.2- times higher in women with an increased level of anxiety symptoms (OR 1.17; %95 CI 1.06-2.13).

Conclusion: Psychological factors such as alexithymia character, neurotic personality, high anxiety, and low social support are helpful in differentiating women with PMS from those without PMS. This study proposes that psychological factors are the main predictors of PMS and should be considered for evaluation and treatment of the illness.

DOI: 10.9734/INDJ/2014/11590

Major depressive disorder is a serious medical illness associated with significant burden. Our current treatments for depression are limited, which has motivated researchers to explore novel targets. This article will highlight new psychopharmacological agents and investigational directions which may show promise in achieving better outcomes and symptom relief for those suffering from depression. This review will address key categories of novel therapeutic targets for depression. The newer and investigational agents involving monoaminergic transmission will be discussed, followed by those with glutamatergic, opioid, anticholinergic, and miscellaneous mechanisms. As the field continues to learn more about the pathophysiology of depression, there will be an emergence of additional innovative targets and investigational mechanisms, along with an improvement in our treatment outcomes.
