Official Title: Clinical, Molecular and Biochemical Characterization of Familial Encephalopathy With Neuroserpin Inclusion Bodies
Brief Summary:
The purpose of this study is to learn more about the medical problems and the genetic factors involved in a recently defined form of inherited dementia called "familial dementia with neuroserpin inclusion bodies (FDNIB)." Abnormal substances in nerve cells of patients with this disease affect brain and nervous system function, causing confusion, memory decline and impaired cognition (thinking ability). Patients also develop movement disorders and, possibly, seizures. Symptoms begin in midlife, between 45 and 55 years of age.
Patients with FDNIB and family members 18 years of age or older at risk for the disease may be eligible for this 3-year study.
Participants will have a medical and family history and review of medical records; interview with a medical geneticist (specialist in genetics); physical, neurological and psychiatric examinations; and the following tests and procedures:
