      Abstract

      Background:

      Intracranial aneurysms most commonly present following rupture causing subarachnoid hemorrhage. Mental disorders are common among patients with unruptured intracranial aneurysms and in aneurysmal subarachnoid hemorrhage survivors. However, to the best of our knowledge, there is no published report of unruptured intracranial aneurysm presenting as a mental disorder.

      Case Description:

      A 69-year-old male without a past history of mental disorders and neurological symptoms presented with a 2-month history of anxiety, sadness, lack of pleasure in usual activities, fatigue, difficulties falling asleep and waking up early in the morning, reduced appetite, and weight loss. The patient was diagnosed with major depressive disorder and antidepressant treatment was initiated. Subsequent non-contrast computed tomography (CT) of the head demonstrated hypointense oval-shaped lesion within the projection of the anterior communicating artery. CT angiography confirmed the diagnosis of a 0.8 × 0.6 cm saccular aneurysm originating from the anterior communicating artery and anterior cerebral artery. The patient underwent microsurgical clipping of the aneurysm. On psychiatric assessment 1 month after the surgery, there were no signs of depressive disorder and antidepressive treatment was discontinued. On follow-up visit 1 year after the surgery, the patient did not have any mood symptoms.

      Conclusions:

      The case indicates that organic brain lesions, including intracranial aneurysms, should be suspected in elderly patients presenting with their first episode of mental disorder.

      Unruptured intracranial aneurysms: natural history, clinical outcome, and risks of surgical and endovascular treatment.

      The management of unruptured intracranial aneurysms is controversial. Investigators from the International Study of Unruptured Intracranial Aneurysms aimed to assess the natural history of unruptured intracranial aneurysms and to measure the risk associated with their repair. Centres in the USA, Canada, and Europe enrolled patients for prospective assessment of unruptured aneurysms. Investigators recorded the natural history in patients who did not have surgery, and assessed morbidity and mortality associated with repair of unruptured aneurysms by either open surgery or endovascular procedures. 4060 patients were assessed-1692 did not have aneurysmal repair, 1917 had open surgery, and 451 had endovascular procedures. 5-year cumulative rupture rates for patients who did not have a history of subarachnoid haemorrhage with aneurysms located in internal carotid artery, anterior communicating or anterior cerebral artery, or middle cerebral artery were 0%, 2. 6%, 14 5%, and 40% for aneurysms less than 7 mm, 7-12 mm, 13-24 mm, and 25 mm or greater, respectively, compared with rates of 2 5%, 14 5%, 18 4%, and 50%, respectively, for the same size categories involving posterior circulation and posterior communicating artery aneurysms. These rates were often equalled or exceeded by the risks associated with surgical or endovascular repair of comparable lesions. Patients' age was a strong predictor of surgical outcome, and the size and location of an aneurysm predict both surgical and endovascular outcomes. Many factors are involved in management of patients with unruptured intracranial aneurysms. Site, size, and group specific risks of the natural history should be compared with site, size, and age-specific risks of repair for each patient.

        The burden, trends, and demographics of mortality from subarachnoid hemorrhage.

        The objective of this study was to describe the recent epidemiology of mortality from subarachnoid hemorrhage in the United States. Subarachnoid hemorrhage is distinct from other forms of stroke in its risk factors, demographics, and treatment. However, it is often clustered with other stroke subtypes, obscuring its unique epidemiology. We analyzed subarachnoid hemorrhage mortality data from the National Center for Health Statistics of the United States for the years 1979 to 1994 and compared it with other stroke subtypes. Age-adjusted mortality rates of subarachnoid hemorrhage were 62% greater in females than in males and 57% greater in blacks than in whites. The median age of death from subarachnoid hemorrhage was 59 years compared with 73 years for intracerebral hemorrhage and 81 years for ischemic stroke. Mortality rates of subarachnoid hemorrhage have decreased by approximately 1% per year since 1979, and the mean age of death has steadily increased from 57 years in 1979 to 60 years in 1994. Subarachnoid hemorrhage accounted for 4.4% of stroke mortality but 27.3% of all stroke-related years of potential life lost before age 65, a measure of premature mortality. The proportion of years of potential life lost due to subarachnoid hemorrhage was comparable with ischemic stroke (38.5%) and intracranial hemorrhage (34.2%). Subarachnoid hemorrhage is an uncommon cause of stroke mortality but occurs at a young age, producing a relatively large burden of premature mortality, comparable with ischemic stroke.

          A systematic review and meta-analysis of magnetic resonance imaging studies in late-life depression.

          Gray matter abnormalities within frontal-subcortical and limbic networks are hypothesized to play a key role in the pathophysiology of late-life depression. In this work, gray matter abnormalities in late-life depression are examined in a systematic review and meta-analysis of magnetic resonance imaging studies. In the systematic review, 27 articles were identified that compared participants with late-life depression with comparison group participants, and 17 studies were suitable for inclusion in meta-analyses of volumes of the whole brain, orbitofrontal cortex, caudate, hippocampus, putamen, and thalamus. Volume reductions were detected in 7 of 15 comparisons of the hippocampus and a meta-analysis revealed a significant, but small, effect size. Although examined by fewer studies, meta-analyses also revealed significant volume reductions in the orbitofrontal cortex, putamen, and thalamus. A more systematic and comprehensive analysis of the global distribution of gray matter abnormalities, and an examination of subcortical abnormalities were identified as key areas for future research.
