Enfermedad de Nasu Hakola: a propósito de los dos primeros casos en Bolivia

Abstract

Both cases meet all the necessary criteria to satisfy a diagnosis of NHD. This is a hereditary, little known disease whose genetic alterations (i.e. mutations) are still in need of further study. It mainly affects males, who suffer the onset of dementia in their thirties. The neurological disorders constitute a frontal syndrome, due to predominant prefrontal involvement, and they occur in the dorsolateral area, with disorders affecting the executive and planning functions; in the orbitofrontal area, which is reflected in social maladjustment and clear obsessive compulsive traits; and also in the medial or cingulate area, which manifests itself as apathy and lack of motivation. When dealing with this disease, in addition to symptomatic therapy, genetic counselling is also important.
