Answer:
Dear
Ivan,
According
to reports in the medical literature, Fahr's Disease or Familial Idiopathic
Basal Ganglia Calcifications is often familial.
Familial
Fahr's Disease may be transmitted as an autosomal recessive trait
or, in other affected families (kindreds), may have autosomal dominant
inheritance.
In other
instances, the condition appears to occur randomly for unknown reasons
(sporadically). Some experts suggest that the condition may sometimes
result from an unidentified infection during pregnancy affecting the
developing fetus (intrauterine infection).
