    Patients with hydrencephalus showed central autonomic failure, unlike those with hydrocephalus who had normal autonomic function. This suggests autonomic failure in some developmental disorders may originate in the brain.

    Area of Science:

    • Neurology
    • Autonomic Nervous System Function
    • Developmental Disorders

    Background:

    • Hydrencephalus and hydrocephalus are distinct neurological conditions affecting cerebrospinal fluid dynamics.
    • Autonomic dysfunction can be a feature of various neurological disorders, but its origin is not always clear.

    Purpose of the Study:

    • To investigate and compare autonomic functions in patients with hydrencephalus versus hydrocephalus.
    • To determine the origin of autonomic failure in patients with these conditions.

    Main Methods:

    • Studied autonomic functions in three patients with hydrencephalus and five with hydrocephalus.
    • Performed histological examination of the autonomic nervous system, including the hypothalamus.

    Main Results:

    Related Experiment Videos

    • Patients with hydrencephalus exhibited autonomic failure of central origin.
    • Patients with hydrocephalus demonstrated essentially normal autonomic function.
    • In hydrencephalus cases, the hypothalamus was abnormal, while other autonomic nervous system components were histologically normal.

    Conclusions:

    • Autonomic failure in some patients with mental and motor retardation can stem from cerebral abnormalities.
    • Hydrocephalus is not associated with the type of central autonomic failure observed in hydrencephalus.
