Organic Depression and Terson's Syndrome in Adult Polycystic Kidney Disease: Case Report and Review of Literature.

Depressive symptoms are common in neurological diseases, at times posing dilemma in organic or functional origin. Cerebrovascular disease may predispose, precipitate, or perpetuate some geriatric depressive syndromes that resemble primary depressions both clinically and therapeutically in about half of the patients following acute stroke. Terson's syndrome is the direct occurrence of vitreous hemorrhage following subarachnoid/subdural hemorrhage, often overlooked in the acute setting. Autosomal dominant (adult) polycystic kidney disease may be associated with berry aneurysms and hypertension, and may lead to intracranial bleeds. We report an unusual case of organic depression and Terson's syndrome in a 50-year-old female with polycystic kidney disease and hypertension, following anterior communicating artery aneurysmal subarachnoid bleed with bilateral subdural extension. Management included anti-hypertensives, antiepileptics, neodymium: YAG laser photocoagulation, and aneurysmal clipping.
