The experience of 500 transcranial Doppler (TCD) sonographies at Siriraj Hospital between April 1988- June 1989 were reported. The indications for TCD study were hemiplegia 156 (31.20%), vertigo 119 (23.80%), transient ischemic attack (TIA) 26 (5.20%), hemihypalgesia 14 (2.80%), dysarthria-dysphagia syndrome 13(2.60%), visual problem 13(2.60%), syncope 10(2.00%), memory loss 8(1.60%), aphasia 6(1.20%), carotid bruit 6(1.20%), miscellaneous (artereovenous malformation, aneurysm, arteritis, carotico-cavernous fistula, tinnitus, etc) 25(5.00%), and healthy subjects 92(18.4%). Abnormal TCD studies were found in various conditions of different percentages, i.e. 91.03 per cent in hemiplegia, 76.47 per cent in vertigo, 65.38 per cent in TIA, 71.43 per cent in hemihypalgesia, 61.54 per cent in dysarthria - dysphagia syndrome, 38.46 per cent in visual problem and 30.43 per cent in normal subject. TCD is noninvasive, safe and painless. It is a useful screening test for prophylaxis of cerebrovascular disease in the elderly.

A 58-year-old female was admitted to our hospital because of orthostatic syncope, and difficulty in urination and walking for 2 years. At age 35, she suffered from cerebral hemorrhage and was diagnosed as Moyamoya disease (MD). Neurological examination on admission revealed severe orthostatic syncope so that she could not stand. At that time, her blood pressure and heart rate were 104/74 mmHg and 78/min in supine position and 52/48 mmHg and 52/min in 60 degrees head-up position. She also had severe pollakisuria, cerebellar ataxia and dysarthria. Cranial nerves, motor strength and deep reflexes were normal. ECG, chest X-ray, and EEG were normal. Aschner, Czermak, and cold pressor tests revealed no response. Urodynamic study revealed autonomic bladder. MRI showed only enlarged fourth ventricle because of atrophy of the pons. Bilateral CAG revealed "Moyamoya" vessels in the cerebral basal regions. Cerebral blood flow (CBF) was measured by 133Xe inhalation method. Mean arterial blood pressure changed from 134 mmHg to 126 mmHg in 45 degrees head-up tilting and CBF decreased from 47.5 mg/100 g/min to 37 ml/100 g/min position. Though there was no relationship between SDS and MD, each one shows dysautoregulation of CBF, it is supposed that a severe orthostatic syncope attack was resulted from synergism of both effects.

Fourteen patients with symptoms of vertebrobasilar insufficiency caused by vertebral artery stenosis in the distal first portion underwent surgical reconstruction. They ranged in age between 42 and 73 years, with a median age of 57 years. Their symptoms included vertigo, dysarthria, syncope, hemiparesis, and homonymous quadrant anopsia. The etiologies of the stenoses involved kinking in 12 cases and mechanical compression due to cervical sympathetic nerve, osteophyte, or fibrous bands in two cases. Digital subtraction angiography revealed that stenosis was maximal at systole and minimal at diastole in six of eight cases. In two of the 14 cases, stenosis was not demonstrated in the neutral position, but stenosis of the left vertebral artery appeared when the head was rotated to the right. Surgical procedures involved 13 decompressions of the vertebral artery and one subclavian artery-vertebral artery bypass using the saphenous vein. Postoperatively, 12 cases of miosis and one of asymptomatic phrenic nerve palsy were observed, but there were no serious complications. All but two patients had complete resolution of their symptoms. Stenosis due to kinking and/or mechanical compression disappeared in all cases after decompression of the vertebral artery. The effects of arterial pulse and neck rotation on vertebral artery stenosis in the distal first portion are discussed.

Symptomatic common carotid artery occlusion (CCAO) is rare. We studied 17 patients with ischemic cerebrovascular symptoms and unilateral CCAO on angiography to help clarify clinical and radiologic features. Mean age was 62 years; 65% were women. Predominant symptoms and signs included visual-ipsilateral monocular or retrochiasmal symptoms (88%), motor weakness (88%), sensory disturbance (59%), dizziness/lightheadedness (53%), and syncope (24%). Dysarthria, headache, or involuntary limb shaking occurred less frequently. Positionally related symptoms occurred in approximately two-thirds of the patients. TIAs were often multiple and preceded a stroke or occurred without subsequent stroke in 82%. Hemispheric TIAs contralateral to the CCAO occurred in 41%. Ten patients (59%) suffered stroke, seven (70%) of which were ipsilateral to the CCAO. Vascular risk factors included cigarette use (76%), hypertension (71%), diabetes mellitus (41%), and hyperlipidemia (41%); 82% had two or more risk factors. Known cardiac disease was present in 59%. CCAO was present at the origin of the vessel in most patients. Most had atherosclerotic narrowing of multiple extracranial large vessels. During follow-up, none of the patients had a spontaneous second infarct; five had TIAs, including two with amaurosis fugax, all in the CCAO territory. More restricted external carotid collaterals may, in part, explain the higher frequency of ipsilateral stroke and contralateral TIAs than reported for internal carotid occlusion.

Neurological symptoms of transient unsteadiness, dysarthria, dysphasia, dysbasia, transient monoor hemiparesis, hemiparesis, scintillating scotomas, amaurosis fugax, vertigo, dizziness, migraine accompaniments, syncope and seizures were the presenting manifestations of thrombocythemia in various myeloproliferative disorders. Erythromelalgia preceded or followed the neurologic ischemic attacks. The neurologic and ocular attacks usually had a sudden onset, lasted for a few seconds to several minutes and occurred independently or sequentially rather than simultaneously. This clinical syndrome is caused by platelet-mediated ischemic and thrombotic processes in the end-arterial microvasculature and reflects the existence of a platelet dependent and aspirin responsive arterial thrombophilia in thrombocythemia as novel disease entity, which confirms and elucidates Mitchell's hypothesis.

We report an autopsy case of multiple system atrophy (MSA) presenting with rapid progression of autonomic disturbance. He was admitted to our hospital because of gait disturbance and dysarthria. The patient was a Japanese man, who first noticed gait disturbance and dysarthria at age 58, followed by syncope 3 months later. He developed urinary incontinence and frequency of urination 8 months after the disease onset. His gait disturbance, dysarthria, syncope, and urinary symptoms progressed, and he was admitted to the department of neurology 1 year after the onset of the disease. He was clinically diagnosed as having MSA and was followed in the outpatient office. He deteriorated rapidly and was readmitted to the department of neurology 19 months after the onset of the disease. Physical examination showed orthostatic hypotension. Neurological examination revealed nystagmus, dysarthria of cerebellar type, increased deep tendon reflexes, bilateral positive Babinski signs, ataxic and spastic gait, mild right hypesthesia and hypalgesia, impotence, constipation, and urinary incontinence. Routine blood examination showed slight anemia, elevated BUN, GOT, and blood sugar. Electrocardiography revealed sinus tachycardia and chest rentogenogram showed cardiac enlargement. Brain MRI showed atrophy of cerebellum and pons, and lacunae in basal ganglia. Autonomic function tests revealed abnormal in head-up tilt test, and CVR-R in May and November 1995. However 123I-MIBG myocardial scintigraphy showed normal uptake of MIBG in May 1995 and decreased uptake in November 1995. He deteriorated rapidly and died in May 1996. Autopsy findings revealed not only prominent olivopontocerebellar and slight striatonigral lesions, but also autonomic lesions with massive appearance of glial cytoplasmic inclusions. He was pathologically verified as having MSA. In the present patient, autonomic nervous system, especially cardiac sympathetic nerve, deteriorated rapidly, which might result in short duration of the illness.

A 68-year-old man was admitted to St Marianna University Hospital on account of loss of consciousness with left hemiplegia. During the hospital recovery course with a rehabilitation procedure, the patient's blood pressure was very unstable, fluctuating between high (210/110 mmHg) and low (110/70 mmHg) values accompanied by a fainting sensation. A second stroke of left hemiplegia took place 1 month later. Afterwards, his condition worsened to tetraplegia with dysarthria. Three months later, lung cancer with multiple metastasis including his left neck was found and he died from adynamic ileus 6 months after the onset of the present illness. Autopsy revealed nearly complete atheromatous obstruction and more than 50% stenosis, respectively, of his right common and internal/external carotid arteries. His intracranial arterial trunks and main branches were all patent with localized atherosclerosis of only moderate degree. The pathology of the brain existed predominantly in the right hemisphere in the border zone area between the anterior and middle cerebral arteries systematically with numerous disseminated foci of complete or incomplete necrosis, white matter and gray matter being involved independently. Involvement of centrum semiovale white matter is more extensive and intensive than that of gray matter. Of the gray matter, cerebral cortex as well as striatum, periventricular (the third ventricle) gray and cerebellar cortex was involved. The specific characteristic topography and distribution of the lesions together with their histopathology are described in detail with illustration. It is concluded that this case represents an outstanding example of hemodynamic cerebral circulatory insufficiency doubly caused by hemilateral carotid artery stenosis and repeated episodes of systemic hypotension.

A post hoc analysis of the risperidone (RIS)/paliperidone (Pali) clinical trials database comprising 64 studies was conducted. Risk of sudden death, cardiovascular (CV), and cerebrovascular events during RIS or Pali treatment was estimated. Treatment emergent CV adverse events were identified using 7 prespecified Standardised MedDRA Queries as follows: embolic/thrombotic events, cerebrovascular disorders, ischemic heart disease, cardiac arrhythmias, cardiac failure, torsades/QT prolongation, and convulsions. Risk in the RIS/Pali pooled group was significantly increased compared to placebo for the following adverse events: syncope, tachycardia, palpitations, edema peripheral, dysarthria, and transient ischemic attack. Incidence of death related to CV events was low and similar across groups. Consistent with the known pharmacologic profile and product information, this analysis of treatment emergent adverse event data from a large, randomized, controlled clinical trials database described increased risk versus placebo for several specific CV events. Apart from events described in existing product labeling, no new safety findings emerged.

Fahr's disease is a rare neuropsychiatric disease characterized by bilateral intracranial calcification, primarily in the basal ganglia. The more general term, Fahr's syndrome, is used for primary and secondary basal ganglia calcification, regardless of the etiology, but the term Fahr's disease is used to describe primary, idiopathic cases. Fahr's disease may present with neurological symptoms, such as parkinsonism and extrapyramidal symptoms, dysarthria, paresis, convulsion, and syncope. Psychiatric disorders, including behavioral disorders, psychosis, and mood disorders, as well as cognitive disorders can occur. CT is useful for the diagnosis of Fahr's disease. Herein we present a patient diagnosed as Fahr's disease that presented with symptoms of depression, delusions, and auditory hallucinations. The 47-year-old male patient was hospitalized in a forensic psychiatry inpatient clinic due to aggressive behavior and was subsequently diagnosed with major depressive disorder with psychotic features. While hospitalized he was treated with antidepressant and antipsychotic drugs, as well as electroconvulsive therapy, resulting in significant improvement in his symptoms. As bilateral basal ganglia calcification was observed via CT, the patient was diagnosed as Fahr's disease. This case report emphasizes the importance of cranial imaging and detailed laboratory examination when evaluating patients with psychosis and affective symptoms. Pathologies such as Fahr's disease must be included in the differential diagnosis, especially in cases with neurological symptoms and cranial imaging findings.

Stylocarotid artery syndrome is a rare condition that results from compression of the internal or external carotid artery by the styloid process of the temporal bone. Here we present the case of a patient suffering from syncope, monoparesis of the right arm, and dysarthria due to recurrent transient ischemic attacks that resulted from severe compression of the midsegment of the left extracranial internal carotid artery between an elongated styloid process and a C2 vertebral body osteophyte. This case demonstrates successful surgical management of a condition rarely encountered by the vascular surgeon.
