Original abstract
We report a case of cerebral amyloid angiopathy(CAA)-related subarachnoid hemorrhage(SAH)with Parkinson's disease dementia(PDD), along with a literature review. CASE: A 67-year-old woman with a history of Parkinson's disease was diagnosed with SAH(World Federation of Neurosurgical Societies grade I). The plain head CT performed on admission, revealed an atypical hematoma distribution. Blood sampling, MRI and cerebral angiography revealed no vascular abnormalities, meningitis, encephalitis, or primary angiitis of the central nervous system. MRI performed on the third day after admission confirmed the presence of bilateral cortical or subcortical hemorrhage in the parietal lobe, with amyloid-related imaging abnormalities. A preliminary diagnosis of CAA was made, based on the Boston criteria. She was also diagnosed with PDD, based on the cognitive decline during hospitalization. CONCLUSION: Stroke related with CAA, as seen in SAH, may contribute to cognitive decline and the progression of lesions in PDD.
