Thalamic–Hypothalamic Dysregulation: Causes, Mechanisms, Clinical Features, Diagnosis, and Implications
Introduction Thalamic–hypothalamic dysregulation refers to impaired functioning of the thalamus and hypothalamus , two critically important structures located deep within the brain. Dysfunction may arise from hypoxic-ischemic injury, viral or bacterial infection, inflammation, trauma, vascular compromise, autoimmune processes, toxic exposures, neurodegenerative disease, tumors, or other neurological insults . Because the thalamus and hypothalamus serve as central regulators of numerous neurological, autonomic, endocrine, cognitive, and behavioral functions, impairment of either structure can produce widespread symptoms. When both regions are affected, the consequences may involve multiple body systems simultaneously, resulting in complex neurological and physiological dysfunction. Thalamic–hypothalamic dysregulation is not a single disease but rather a descriptive term for a pattern of dysfunction affecting interconnected neural networks that regulate consciousness, sensation, cog...
