Post-Stroke Neuropsychiatric Complications: Types, Pathogenesis, and Therapeutic Intervention

Area of Science:

• Neuroscience
• Psychiatry
• Rehabilitation Medicine

Background:

• Stroke survivors frequently experience physical disabilities and neuropsychiatric disturbances.
• These complications include neurological issues like pain, epilepsy, and dementia, and psychiatric disorders such as depression, anxiety, apathy, and fatigue.

Purpose of the Study:

• To review the risk factors, underlying mechanisms, and current treatment strategies for post-stroke neuropsychiatric complications.
• To highlight the need for further research to improve therapeutic interventions.

Main Methods:

• Literature review of recent studies on post-stroke neuropsychiatric complications.
• Analysis of identified risk factors, biological mechanisms, and pharmaceutical/rehabilitative treatments.

Main Results:

• Identified risk factors include age, gender, lifestyle, stroke characteristics, medication, lesion location, and comorbidities.
• Key underlying mechanisms involve inflammatory response, HPA axis dysregulation, cholinergic dysfunction, serotonin deficiency, excitotoxicity, and mitochondrial dysfunction.
• Current treatments like anti-inflammatories, acetylcholinesterase inhibitors, SSRIs, and rehabilitation show promise but require further validation.

Conclusions:

• Post-stroke neuropsychiatric complications are multifactorial, involving various biological pathways.
• Existing treatments offer some benefit, but their efficacy remains debated.
• Urgent, comprehensive research is needed to develop more effective strategies for managing these debilitating conditions.
