[Behavioural problems and personality change related to cerebral amyloid angiopathy]

Cerebral amyloid angiopathy (CAA) belongs to the group of amyloidoses that are characterized by the deposition of insoluble and tissue-damaging amyloid proteins. Spontaneous intracerebral hemorrhage is the common clinical presentation of CAA resulting from the degenerative effect of beta amyloid on the cerebral vascular system. Though CAA is rather a neurological disease psychiatric symptoms can occur and even dominate the clinical picture.A case report is presented in order to illustrate the association between CAA and psychiatric symptoms.We report the case of a 54-year-old female patient with radiologic references to a probable CAA and mild cognitive impairment who developed behavioural difficulties and personality change that necessitated a psychiatric treatment. Psychiatric symptoms were most likely due to CAA.CAA can be associated with psychiatric symptoms and hence should be considered in the treatment of elderly patients with behavioural problems or personality changes. Diagnostic neuroimaging and examination of cerebrospinal fluid is recommended.
