Background:Dementia is the most devastating cognitive disorder of the elderly and needs extra attention to care. Therefore, this study was conducted to identify the caregiver burden of dementia key caregivers and their Quality of Life (QOL).Materials and Methods:Sample consisted of purposively selected 24 dementia key caregivers fulfilling the inclusion criteria from the in-patient of the Department of Geriatric Mental Health, King George's Medical University, Lucknow, Uttar Pradesh, India. Zarit Burden Interview and World Health Organization QOL-BREF were administered. Mean, standard deviation, t-test, Chi-square with Yate's correction were used to analyze the data.Results:All key caregivers felt mild to moderate level of burden. Gender-wise significant difference was found on burden area of expectation (P < 0.05). Mean scores on physical, psychological, social relationship, and environmental QOL were found to be on lower side. A negative correlation was found between burden and QOL.Conclusion:Professional help and supportive psychotherapy can be provided to the key caregivers of dementia patients to reduce their burden, strengthen the coping skill and thus improve their QOL.

Background:Depression is the most common mental health problem across all the age groups. Still diagnostic techniques and laboratory tests are awaited to confirm it. Some studies focus on P300 latency to aid in the diagnosis of depression. Hence, this study was conducted to know whether P300 latency is an indicator of major depressive disorder (MDD).Methods:This study was conducted both on patients admitted in the hospital and those attending outdoor clinic giving written informed consent and fulfilling inclusion/exclusion criteria from the Department of Psychiatry, S.N. Medical College and Hospital, Agra. The sample consisted of 30 consecutive patients suffering from MDD as per the Diagnostic and Statistical Manual of Mental Disorders, Fourth Edition criteria and 30 subjects as normal control. Sociodemographic and clinical history proforma, Hamilton Rating Scale for Depression (Ham-D), and P300 were administered on all 60 subjects. Data were analyzed using mean, standard deviation, and t-test.Results:Significant difference (P < 0.0001) has been found in HAM-D mean scores of depressed and nondepressed control group subjects. The mean score of depressed group was significantly high (18.066) compared to nondepressed control group (4.833). Significant difference (P < 0.0001) between the mean of P300 latency in depressed and nondepressed control subjects was also found. Mean score of P300 latency in depressed group was significantly high (346.918 ± 19.515) compared to the nondepressed control subjects (303.741 ± 6.378). There was a significant difference in the mean of P300 latency between mild and severe (P < 0.0001), mild and very severe (P < 0.0003), as well as moderate and severe (P < 0.0001) level of depression.Conclusions:P300 latency may be used as an indicator of MDD and it is directly proportional to the severity of MDD.

Alzheimer’s disease (AD) is the most common cause of dementia and accounts for approximately 50% to 80% of all cases of dementia. The diagnosis of probable AD is based on clinical criteria and overlapping clinical features pose a challenge to accurate diagnosis. However, neuroimaging has been included as a biomarker in various published criteria for the diagnosis of probable AD, in the absence of a confirmatory diagnostic test during life. Advances in neuroimaging techniques and their inclusion in diagnostic and research criteria for the diagnosis of AD includes the use of positron emission tomography (PET) imaging as a biomarker in various therapeutic and prognostic studies in AD. The development and application of a range of PET tracers will allow more detailed assessment of people with AD and will improve diagnostic specificity and targeted therapy of AD. The aim of this review is to summarize current evidence on PET imaging using the non-specific tracer [18F]fluorodeoxyglucose and specific tracers that target amyloid and tau pathology in people with AD.

Here, we are reporting a case of late onset mania in a 61 year old male secondary to dengue fever. The past and family history of the mood disorder was absent in the patient. Episode of mania had a temporal correlation with the dengue fever. Psychiatric co-morbidities are mentioned in the literature following dengue fever but the literature on the mania following dengue is sparse. The late onset mania in dengue fever is unreported in the literature.
