Аннотация
INTRODUCTION: Disorders affecting sleep and the circadian rhythm, autonomic clinical signs and symptoms, and neuroendocrine alterations are frequent characteristics in Huntington's disease, some of which present in early stages of the disease. It is reasonable to think that some of these features could result from a hypothalamic dysfunction affecting the centre regulating sleep, metabolism and the autonomic nervous system.
AIM: The study presents the evidence available to date that suggests the involvement of a hypothalamic disorder in Huntington's disease.
DEVELOPMENT: Histopathological, hormonal and neuroimaging research relates this area of the brain to Huntington's disease. The experimental findings and those obtained with animal models or in studies conducted with patients are summarised. Likewise, the clinical repercussions (sleep and circadian rhythm disorders, psychiatric and cognitive pathologies, and the clinical signs and symptoms linked to autonomic dysfunction) secondary to possible involvement of the hypothalamus in this disease are also described.
CONCLUSIONS: The hypothalamus acts as a centre that integrates the neuroendocrine and autonomic functions, and plays a significant role in cognitive and behavioural signs and symptoms. Disorders of this type have been highlighted in Huntington's disease. Further studies are needed to elucidate the role and scope of this region of the brain in this disease.
