A case of primary neuroleptospirosis.

143 may show a high T2 signal in the basal ganglia and caudate atrophy. Normal plasma lipid levels and lipoprotein electrophoresis help to distinguish this from abetalipoproteinaemia [4,6,8]. Proper evaluation of movement disorders in young people is necessary as there are important considerations regarding diagnosis, treatment and family counselling. Paroxysmal dyskinesias are commonly mistaken for seizures. Chorea and cognitive impairment in neuroacanthocytosis can mimic Huntington disease, with implications for genetic counselling [6,8]. Dyskinesias and dystonias interfere with activities of daily living and occupation, leading to disability and handicap. Appropriate management depends on accurate diagnosis. As shown by these cases, the diagnosis can sometimes be established on clinical grounds or with simple investigations.
