Apathy occurs frequently in neuropsychiatric disorders both as a symptom of other syndromes and as a syndrome per se. Histories are presented of patients with a syndrome of apathy who showed clinically significant, sustained benefit from pharmacological treatment. Etiologies included non-Alzheimer's frontal lobe dementia, cerebral infarction, intracranial hemorrhage, alcoholism, and traumatic brain injury. Agents included amantadine, amphetamine, bromocriptine, bupropion, methylphenidate, and selegiline. These histories support the suggestion that apathy is a discriminable dimension of behavior having its own pathophysiology and implications for psychiatric care. They raise the possibility of treatment for many patients previously thought untreatable. Studying the treatment of apathy may contribute to the clinical care and scientific understanding of neuropsychiatric disorders throughout the life span.

1. We examined 156 patients 33 years after CO poisoning occurred at the Miike Mikawa Mine, Fukuoka, Japan. The subjects were classified according to age as follows: between 55 and 59 years (n = 14), 60 and 69 years (n = 62), 70 and 79 years (n = 60), and 80 and 87 years (n = 18). The mean age was 69.2 years old. Concerning the duration of coma that occurred soon after the accident, 64 remained comatose from 0 to 6 hours, 46 from 6 to 12 hours and 46 from 12 to 48 hours. 2. Subjective symptoms were observed in 96.8% of the patients. Among them, forgetfulness was noted in 89.7%, followed by irritability in 66.7%, headache in 59.6%, insomnia in 55.8%, limb pain in 46.8%, dull head feeling in 42.9% and dizziness in 36.5%. 3. Intellectual disturbances were observed in 68.6% of the patients, including impression disturbance in 58.3%, memory disturbance in 51.9%, calculation disturbance in 63.5%, thinking disturbance in 61.5% and disorientation in 14.1%. 4. Apathy and disorder of volition and interest which were found in 72.4% were included in personality change because all symptoms persisted for many years. Personality change was classified as follows: weakness of emotion and will (hypobulia) in 54.4%, infantilism in 35.2%, hyperactive, talkactive and lack of inhibition in 18.5%, lack of self-possession and unstable temper in 9.6%, depression in 15.3%, neurosis in 7.6% and schizophrenic state in 2.5%. Among these symptoms of personality change, weakness of emotion and will and infantilism were conspicuous among the patients who remained in a coma for more than 6 hours soon after the accident but showed no relationship with age. 5. Neurological symptoms that were found in 48.7% of the patients were classified as sensory disturbance in 25.6%, peripheral nerve symptoms in 16.0%, pyramidal symptoms in 14.1%, ataxia and cranial nerve symptoms in 7.1%, paroxysmal symptoms in 6.4% and focal symptoms in 4.5%, extrapyramidal symptoms in 21.8% (Parkinsonism in 4.5%, tremor in 10.9% and muscle rigidity in 16.0%) and vegetative symptoms in 37.2%. 6. At the time of investigation, 5 CO poisoning patients were classified as serious cases (3.2%), 20 as comparatively serious (12.8%) medium-degree cases, 28 as comparatively mild (17.9%) medium-degree cases, 37 as comparatively serious (23.7%) mild cases, 42 as comparatively mild (26.9%) mild cases, 24 (15.4%) as having symptoms which were not problematic, and 24 (15.4%) as having symptoms that markedly worsened due to complication. 7. A total of 138 (88.4%) cases had complications were classified as follows: 78 cases (50.0%) of hypertension, 62 cases (39.7%) of cerebral infarction, 24 cases (15.4%) of cardiac disturbance, 21 cases (13.5%) of diabetes mellitus, 14 cases (9.0%) of hepatic disturbance and six cases of silicosis (3.8%). 8. Cranial MRI was carried out for 129 cases (82.7%). Of the abnormal findings identified, cerebral atrophy accounted for 72.0% (93 cases), including moderate and severe cases in 47.2% (61 cases), pallidum lesion for 37.9% (49 cases), lacunar infarction (including cerebral infarction) for 52.7% (68 cases), and hippocampal atrophy for 18.6% (24 cases). Many cases of cerebral atrophy and hippocampal atrophy were observed in patients who remained in the initial coma for more than 12 hours and were 80 years of age or old. The cases of pallidum lesion were observed in patients who remained in the initial coma for more than 6 hours, and no relationship with age was found. The other findings, cerebral atrophy and lacunar infarction showed a slight relationship with age. 9. Among the moderate and serious cases of intellectual disturbance, cerebral atrophy constituted to 62.5%, lacunar infarction 68.7% and pallidum lesion 50.0%. Among the moderate and serious cases of personality change, cerebral atrophy constituted 78.5%, lacunar infarction 35.0% and pallidum lesion 50.0%. Moreover, among extrapyramidal symptoms, pallidum lesion constituted 58.6%, cerebral atrophy 55.1% and lacun

We report an 81-year-old patient with progressive dementia, disinhibition, and gait disturbance. He showed visuospacial disorientation, apathy, and gait disturbance at 76 years of age. When he was 77 years old, he was diagnosed Parkinson's disease and treated with the 1-dopa, the dopamine agonist, the amantadin, and the anti-cholinergic drug. These treatments didn't improve his motor disturbances. His motor disturbances, apathy, and abnormal behavior progressed gradually. He was admitted to the hospital at the age of 77. He was severely demented and akinetic. Sometime, violent behavior and hallucination were seen. The brain MRI showed frontotemporal lobe atrophy and severe leukoaraiosis of the frontal white matter. At 79 years of age, he became mute and bedridden. When he was 80 years old, large infarction occurred in his occipital lobe. He died due to renal failure and respiratory suppression at 81 years of age. His brain was examined pathologically. At the neurological CPC, the chief discussant arrived at the conclusion that his diagnosis was Binswanger's disease. Other possibilities discussed were FTD, CBD, and progressive subcortical gliosis. The post-mortem examination revealed diffuse white matter degeneration due to atherosclerotic change of the small artery, many lacunar infarctions, and severe infarction of the occipital lobe. These findings led the diagnosis of Binswanger's disease and cerebral infarction.

Anterograde amnesia due to infarction of the anterior fornix is a rare but unique neuropsychological syndrome. Only 2 cases have been reported previously. Lacking focal neurologic deficits, this syndrome is not easy to diagnose. Moreover, it is not fully recognized by the clinicians, making its diagnosis all the more difficult. Here we report a patient of infarction of the anterior fornix and genu of the corpus callosum who developed sudden apathy and anterograde amnesia. Unfortunately, the patient was initially diagnosed and treated as an acute psychiatric disorder by a psychiatrist, and treatment for acute cerebral infarction could not be performed. This case emphasizes the importance of suspecting this syndrome and performing brain magnetic resonance imaging immediately in the patients presenting with anterograde amnesia of sudden onset.

Dopamine D2/3 receptor agonists have been widely used to treat motor symptoms in Parkinson's disease and are also reported to improve cognitive and emotional disturbances. Here we describe a patient who developed severe apathy after cerebral infarction in the prefrontal cortex. After administration of ropinirole, his verbal output and spontaneity in daily life was improved remarkably. This improvement was associated with increased blood flow in the prefrontal cortex and basal ganglia. We suggest that ropinirole may be a treatment option for deficits in motivated behavior after prefrontal damage.

Although aneurysmal subarachnoid hemorrhage (aSAH) accounts for only 3-5% of all strokes, a high degree of morbidity has been reported in this relatively young subset of patients. Neuropsychiatric disturbance has often been neglected in these reports. We aimed to investigate the pattern and pathological factors of chronic neuropsychiatric disturbance in aSAH patients. This cross-sectional observational four-center study was carried out in Hong Kong. Neuropsychiatric outcome (Neuropsychiatric Inventory Chinese Version [CNPI]) assessments were conducted cross-sectionally 1-4 years after ictus. Pathological factors considered were early brain injury as assessed by admission World Federation of Neurosurgical Societies grade, aneurysm treatment (clipping versus coiling), delayed cerebral infarction, and chronic hydrocephalus. One hundred and three aSAH patients' spouses or caregivers completed the CNPI. Forty-two (41%) patients were reported to have one or more domain(s) of neuropsychiatric disturbance. Common neuropsychiatric disturbance domains included agitation/aggression, depression, apathy/indifference, irritability/lability, and appetite/eating disturbance. Chronic neuropsychiatric disturbance was associated with presence of chronic hydrocephalus. A subscore consisting of the five commonly affected domains seems to be a suitable tool for aSAH patients and should be further validated and replicated in future studies.
