Affective Disorder and Functional Status as well as Selected Sociodemographic Characteristics in Patients with Multiple Sclerosis, Parkinson's Disease and History of Stroke

Risk of depression after Parkinson's disease, stroke, multiple sclerosis, and migraine in an Iranian population and assess psychometric characteristics of three prevalent depression questionnaires

Objective

We aim to evaluate the prevalence of depression in disorders including multiple sclerosis (MS), Parkinson's disease (PD), migraine, and stroke. Also, we detect risk factors for depression occurrence within each disorder. Moreover, we compare the risk factors in these four common neurologic disorders. In advance, we assess the three surveys in order to better comprehend their distinctions.

Background

Depression is a globally prevalent Psychologic disorder and common co-morbidity in neurological diseases. However, it is mostly underdiagnosed in chronic patients and causes numerous adverse effects.

Methods

We used the database of neurology specialty clinics in a hospital in Tehran, the largest city of Iran. Five hundred nineteen patients, including 105 PD patients, 101 patients with stroke, 213 cases with MS, and 100 Migraine patients, were assessed. They were asked about their chief characteristics and disease-specific variables that may cause depression. Moreover, depression criteria were measured with three internationally used scales to study their variances.

Results

Overall, the prevalence of depression in PD, stroke, MS, and migraine, according to the BDI-II scale, were 43.8%, 38.6%, 45.1%, 37.6%, and according to HDRS scale, were 56.2%, 51.5%, 39.4%, and 43.6% respectively. Finally, according to DSM-XC the depression prevalence were 64.8%, 34.7%, 36.2%, and 67.3% respectively. Possible risk factors of depression were lower educational level, disease severity, socioeconomic level, marital or employment status, female gender, higher age, and consumption of some specific drugs.

Conclusion

Depression is a widespread disorder in chronic neurologic conditions. Our data suggests the odds of depression in neurologic disorders depend on the characteristics of the patient and the features of the disease.

Epigenetic and Coping Mechanisms of Stress in Affective Disorders: A Scoping Review

This review aims to explore the intricate relationship among epigenetic mechanisms, stress, and affective disorders, focusing on how early life experiences and coping mechanisms contribute to susceptibility to mood disorders. Epigenetic factors play a crucial role in regulating gene expression without altering the DNA (deoxyribonucleic acid) sequence, and recent research has revealed associations between epigenetic changes and maladaptive responses to stress or psychiatric disorders. A scoping review of 33 studies employing the PRISMA-S (Preferred Reporting Items for Systematic Reviews and Meta-Analyses-Statement) guidelines investigates the role of stress-induced epigenetic mechanisms and coping strategies in affective disorder occurrence, development, and progression. The analysis encompasses various stress factors, including childhood trauma, work-related stress, and dietary deficiencies, alongside epigenetic changes, such as DNA methylation and altered gene expression. Findings indicate that specific stress-related genes frequently exhibit epigenetic changes associated with affective disorders. Moreover, the review examines coping mechanisms in patients with bipolar disorder and major depressive disorder, revealing mixed associations between coping strategies and symptom severity. While active coping is correlated with better outcomes, emotion-focused coping may exacerbate depressive or manic episodes. Overall, this review underscores the complex interplay among genetic predisposition, environmental stressors, coping mechanisms, and affective disorders. Understanding these interactions is essential for developing targeted interventions and personalized treatment strategies for individuals with mood disorders. However, further research is needed to elucidate specific genomic loci involved in affective disorders and the clinical implications of coping strategies in therapeutic settings.

Mood Disorders

PURPOSE OF REVIEW

This comprehensive review of mood disorders brings together the past and current literature on the diagnosis, evaluation, and treatment of the depressive and bipolar disorders. It highlights the primary mood disorders and secondary neurologic causes of mood disorders that are commonly encountered in a clinical setting. As the literature and our understanding evolve, recent additions to the current literature are important to bring forth to the readers.

RECENT FINDINGS

Advancements in clinical medicine have strengthened our understanding of the associations of neurologic and psychiatric diseases. This article highlights the medications frequently used with newly identified mood disorders and the common side effects of these medications. A paradigm shift has moved toward newer treatment modalities, such as the use of ketamine, repetitive transcranial magnetic stimulation, and complementary and alternative medicine. The risks and benefits of such therapies, along with medications, are reviewed in this article.

SUMMARY

Mood disorders are extraordinarily complex disorders with significant association with many neurologic disorders. Early identification of these mood disorders can prevent significant morbidity and mortality associated with them. With further expansion of pharmacologic options, more targeted therapy is possible in improving quality of life for patients.

Isolation Related to the COVID-19 Pandemic in People Suffering from Parkinson's Disease and Activity, Self-Assessment of Physical Fitness and the Level of Affective Disorders

Background: Staying at home for long periods and limiting various types of activities and social contacts due to the COVID-19 pandemic may have negative consequences for health. This is especially true for people suffering from chronic diseases, in whom an appropriate level of activity and social contacts delay the progress of the disease. This group includes people diagnosed with Parkinson’s disease—PD. Aim: It was decided to investigate the effect of COVID-19 isolation related to self-assessment of physical fitness, physical activity, and the level of anxiety and depression in people with PD. Methods: The study included 30 patients diagnosed with Parkinson’s disease. We compared the results of the pre-pandemic questionnaire and the telephone interview with the same questions—after the period of isolation due to COVID-19. The questionnaire included questions about physical activity and fitness self-assessment. The level of affective disorders was tested using HADS. Results: There was a statistically significant decrease in the physical activity of the respondents after isolation related to COVID-19 (p < 0.05). Self-assessment of physical fitness also decreased, but the differences were not statistically significant. In the post-isolation study, only 50% of the respondents had normative values for anxiety and only 40% for depression. The analysis showed that the level of physical activity—the independent variable, explains anxiety in 30% and depression in 27%. Conclusions: Pandemic isolation has significantly reduced physical activity in PD patients. There was a certain drop in the self-esteem of physical fitness in these people. Physical fitness is an important predictor of preventing the affective disorders of anxiety and depression. The effects of isolation due to COVID-19 require further research.

The Impact of Depression Symptoms in Patients with Parkinson's Disease: A Novel Case-Control Investigation

Parkinson's disease is a common neurodegenerative disease and it is known to cause motor disturbances associated with musculoskeletal problems of the locomotor apparatus, and non-motor symptoms, that are believed to have a harmful effect on health, social functioning and mobility. The aim of this study was to evaluate depression in patients with Parkinson's Disease (PD) compared to subjects who do not have it. The sample consisted of 124 participants (mean age 69.18 ± 9.12). Patients with PD were recruited from a center of excellence for Parkinson's disease (cases n = 62) and healthy subjects without PD from their relatives and caregivers (control n = 62). The Spanish version of Beck's Depression Inventory (BDI) scores and categories were collected. A clear statistically significant difference (p < 0.05) was evident in the BDI scores between both groups. Parkinson's patients presented worse results on the BDI = 15.48 ± 7.24 points compared to healthy subjects with BDI = 7.03 ± 6.99 points. Regarding BDI categories, there were statistically significant differences (p < 0.001) for the greater BDI categories in the Parkinson's group compared with healthy subjects. The depression represents an important potential risk for increased symptoms and negative impact among patients with PD compared with healthy subjects.
