Cardiac effects and comorbidities of neurological diseases

Neurological disorders encompass a complex and heterogeneous spectrum of diseases affecting the brain, spinal cord, and peripheral nervous system, each presenting unique challenges that extend well beyond primary neurological symptoms. These disorders profoundly impact cardiovascular health, prompting an intensified exploration into the intricate interconnections between the neurological and cardiovascular systems. This review synthesizes current insights and research on cardiovascular comorbidities associated with major neurological conditions, including stroke, epilepsy, Parkinson's disease, multiple sclerosis, and Alzheimer's disease. The cardiovascular sequelae of these neurological disorders are multifactorial. For instance, strokes not only predispose individuals to arrhythmia and heart failure but also exacerbate preexisting cardiovascular risk factors. Similarly, epilepsy is associated with autonomic dysregulation and an elevated risk of sudden cardiac death, underscoring the necessity for vigilant cardiac monitoring in affected individuals. Parkinson's disease manifests with orthostatic hypotension and cardiac sympathetic denervation, significantly contributing to morbidity. Additionally, multiple sclerosis and Alzheimer's disease exhibit cardiovascular autonomic dysfunction and heightened cardiovascular risk, underscoring the need for proactive management strategies. Mechanistically, these conditions disrupt autonomic nervous system regulation, induce chronic inflammation, and may share genetic susceptibilities, each contributing to cardiovascular pathology. Effective management of these complexities requires an integrative approach that includes risk factor modification, pharmacotherapy, lifestyle interventions, and comprehensive patient education. Future research directions include identifying novel therapeutic targets, conducting large-scale clinical trials, and investigating genetic biomarkers to individualize treatment strategies. By addressing the multifaceted interactions between neurological disorders and cardiovascular health, healthcare providers can optimize patient care, reducing cardiovascular morbidity and mortality in this vulnerable population.
