We report a 67-year-old man with rt. hand resting tremor and rigidity after lt. putaminal hemorrhage. He had hypertension and alcoholic liver cirrhosis as past history. When he was 62 years old, he realized rt. hemiplegia suddenly and admitted in Juntendo Urayasu hospital. Brain CT showed intracranial hemorrhage in lt. putamen. He was treated with neurosurgery operation for rejecting hemorrhage. Mild rt. hemiparesis remained but he could live independently. He was medicated sulpiride for depression after cerebrovascular accident. On 63 years old, resting tremor and rigidity appeared on his rt. hand. His doctor stopped sulpiride and treated with L-Dopa/Benserazide and trihexiphenidyl. His parkinsonism was stable with this treatment for four years. His doctor considered that he was Parkinson's disease or drug-induced parkinsonism. On 67 years old, he became akinetic-mutism state suddenly and admitted in the hospital. His consciousness turned alert soon and discharged after two weeks. This episode was considered as epilepsy. After one week from discharge, he was found cardio-pulmonary arrest and confirmed dead in the hospital. Post-mortem examination revealed necrosis in the posterior-lateral part of lt. putamen due to hemorrhage. However, there was no degenerative change of the striatum or the substantia nigra and no Lewy bodies in his brain. Other pathological changes were also not found. His parkinsonism might be caused putaminal pathology due to hemorrhage.

The psychopathology of stroke encompasses several psychiatric and behavioral disorders that have high prevalence in the geriatric population, reduce the patient autonomy and increase the caregiver's burden. These disorders are usually associated with other cognitive and neurological deficits, and are labelled as neuropsychiatric when the whole clinical picture is consistent with the specific dysfunction of a neural system or brain region. Thus the neuropsychiatry of stroke comprises disorders of the perception/identification of the self and the environment (anosognosia of hemiplegia, misidentification syndromes, confabulations, visual hallucinations, delirium and acute confusional state), amotivational syndromes (apathy and athymhormia), disorders of emotional reactivity (blunted affect, emotional incontinence, irritability, catastrophic reactions), poor impulse or ideation control (mania) and personality changes. The clinical profile of the subcortical vascular dementia also points to specific brain dysfunction (frontal-subcortical pathways) that manifests with behavioral (depression, emotionalism, irritability) and cognitive symptoms (psychomotor retardation, attention, executive and memory deficits). However, post-stroke depression and anxiety, which have a more variable clinical presentation and might be assimilated, for several aspects, to post-traumatic or adaptive disorders, are disorders less characterized in their neural correlates.

This study presents the result of the studies explaining the effects of acupuncture on various systems and symptoms. It has been determined that endomorphin-1, beta endorphin, encephalin, and serotonin levels increase in plasma and brain tissue through acupuncture application. It has been observed that the increases of endomorphin-1, beta endorphin, encephalin, serotonin, and dopamine cause analgesia, sedation, and recovery in motor functions. They also have immunomodulator effects on the immune system and lipolithic effects on metabolism. Because of these effects, acupuncture is used in the treatment of pain syndrome illnesses such as migraine, fibromyalgia, osteoarthritis, and trigeminal neuralgia; of gastrointestinal disorders such as disturbance at gastrointestinal motility and gastritis; of psychological illnesses such as depression, anxiety, and panic attack; and in rehabilitation from hemiplegia and obesity.

This is the case report of a 44-year-old woman presented with an acute stroke immediately after electroconvulsive therapy (ECT). The patient had no significant medical history other than chronic depression. She was taking sertraline, and she had had multiple previous ECT treatments without any complications. While being monitored in the recovery room within 10 minutes after the last ECT session, she was found to have sudden onset of left-sided flaccid hemiplegia and numbness along with slurred speech. On arrival to our hospital, she was found to have flaccid hemiplegia on the left side involving the face, arm, and leg (face and arm more than the leg involvement), severe dysarthria, and mild neglect syndrome (National Health Institute Stroke Scale of 14). Noncontrast computed tomography (CT) of the head showed no signs of early ischemia, and iodine contrast CT angiography revealed right middle cerebral artery (MCA) (distal M1 segment) clot. Patient received intravenous recombinant tissue plasminogen (rt-PA) at 2.5 hours after the onset of symptoms, and then a total of 3.0 mg of intra-arterial (IA) rt-PA. Angiography at the end of the procedure showed successful recanalization of the M1 segment and normal vessel caliber with adequate distal flow. After the procedure, the patient made rapid improvements in all of her initial symptoms during the first 24 hours. An extensive stroke workup failed to reveal any cause of the stroke, including usual stroke and hypercoagulable risk factors. This was an acute embolic stroke immediately following an ECT, and without the aggressive thrombolytic therapy, the patient's outcome would have been poor because there was an M1 segment clot with a major MCA syndrome with relatively high National Institute of Health Stroke Scale. The neurological side effect profile of ECT is reported to be minimal with most common symptoms being headache, disorientation, and memory complaints. There is no clear cause-and-effect relationship in this case, and the stroke after ECT is extremely rare. In such rare event of stroke while receiving ECT, there is an effective treatment available using both intravenous and IA thrombolysis as reported in this case.

Erasmus Darwin was the founder of evolutionary biology, a renown poet, an inventor, and a general medical practitioner. Erasmus Darwin wrote specifically about the evolutionary and phylogenetic development of the nervous system, neuroembryology, psychiatric illness (including delusions and depression), and electrical therapy for childhood hemiplegia. He conducted experiments in neuro-ophthalmology and wrote about color vision, afterimages, the blind spot, and visual memory.

Familial hemiplegic migraine (FHM) is a rare, dominantly inherited subtype of migraine with aura, where hemiplegia occurs during the aura phase. Mutation screening of families with FHM has revealed a range of different mutations. The mutated FHM genes code for ion transport proteins. Animal and cellular studies have associated the mutated FHM genes with disturbed ion homeostasis, altered cellular excitability and altered neurotransmitter release. Abnormal cortical excitability due to dysfunctional ion-channels might facilitate cortical spreading depression (CSD) and thereby migraine aura and migraine headache. Genotyped FHM patients offer us the chance to study the interplay between genotype and phenotype and may be regarded as a genetic migraine model. FHM studies might open for a better understanding of the molecular migraine pathology, and potentially help to unravel the pathogenesis of the more common migraine forms. We have therefore studied genotyped FHM patients to understand the effect of genotype on the response to migraine provoking substances. We show here that two known migraine triggers failed to induce more migraine aura or migraine headache in FHM-patients than in healthy controls, thus indicating that the FHM genotype does not confer hypersensitivity to these migraine triggers. This has implications for our understanding of the headache mechanisms and raises the question whether FHM share neurobiological background with the common types of migraine. The aims of the present thesis were to test the hypothesis that FHM mutations might be associated with hypersensitivity to known migraine triggers and, thereby, share pathophysiological pathways with the common types of migraine, but our results disprove this hypothesis. Thus, FHM seems very different from MO and MA, both genetically and pathophysiologically. The fact that FHM genes regulate ion homeostasis cannot be extrapolated to the common types of migraine.

Multiple sclerosis (MS) is the most frequent demyelinating disease of the central nervous system, with versatile manifestations--relapsing-remitting or progressive--and an unpredictable course, with prognoses ranging from minimal neurological impairment to severely disabled. Disease modifying agents can minimize relapse rate and slow disease progression. Yet most patients suffer relapses and progression despite use of these agents. Several of the manifestations of MS may cause overall decrease in the performance of the aviator. These include cognitive impairment, fatigue, and depression. Episodes of spasms, dysarthria, ataxia, parasthesias, diplopia, and hemiplegia, as well as drug side effects may also affect flight. Seizures and episodes of vertigo may occur suddenly and result in in-flight incapacitation. We present our experience with two aviators with definite MS and a navigator with probable MS. The various manifestations of MS are specifically addressed with an emphasis on the aeromedical implications.

Familial hemiplegic migraine type 1, a monogenic migraine variant with aura, is linked to gain-of-function mutations in the CACNA1A gene encoding Ca(V)2.1 channels. The S218L mutation causes severe channel dysfunction, and paroxysmal migraine attacks can be accompanied by seizures, coma, and hemiplegia; patients expressing the R192Q mutation exhibit hemiplegia only. Familial hemiplegic migraine knock-in mice expressing the S218L or R192Q mutation are highly susceptible to cortical spreading depression, the electrophysiological surrogate for migraine aura, and develop severe and prolonged motor deficits after spreading depression. The S218L mutants also develop coma and seizures and sometimes die. To investigate underlying mechanisms for these symptoms, we used multielectrode electrophysiological recordings, diffusion-weighted magnetic resonance imaging, and c-fos immunohistochemistry to trace spreading depression propagation into subcortical structures. We showed that unlike the wild type, cortical spreading depression readily propagated into subcortical structures in both familial hemiplegic migraine type 1 mutants. Whereas the facilitated subcortical spread appeared limited to the striatum in R192Q, hippocampal and thalamic spread was detected in the S218L mutants with an allele-dosage effect. Both strains exhibited increased susceptibility to subcortical spreading depression and reverberating spreading depression waves. Altogether, these data show that spreading depression propagates between cortex, basal ganglia, diencephalon, and hippocampus in genetically susceptible brains, which could explain the prolonged hemiplegia, coma, and seizure phenotype in this variant of migraine with aura.

Hemiconvulsion-hemiplegia-epilepsy syndrome involves sudden and prolonged unilateral seizures, followed by transient or permanent hemiplegia and epilepsy during infancy or early childhood. Some patients with familial hemiplegic migraine and demonstrating the S218L mutation in CACNA1A experience severe attacks with unilateral cerebral edema after trivial head trauma. We report on a 5-year-old Japanese girl presenting with hemiconvulsion-hemiplegia-epilepsy syndrome after infection with parvovirus B19. Magnetic resonance imaging performed 2 days after admission revealed cerebellar atrophy and marked hyperintensity in the left hemisphere on T(2)-weighted and diffusion-weighted imaging. Magnetic resonance angiography performed 7 days after admission demonstrated obliteration of the left proximal middle cerebral artery in the acute phase. However, this finding was not evident on brain angiography performed 25 hours after magnetic resonance angiography. Genetic analysis of familial hemiplegic migraine revealed a heterozygous S218L mutation in CACNA1A. Taken together, these results suggest that vasospasms of cerebral vascular smooth muscle, with possible cortical spreading depression, may have caused the hemiconvulsions and hemiplegia in the left hemisphere. This case report is the first, to the best of our knowledge, to associate CACNA1A with hemiconvulsion-hemiplegia-epilepsy syndrome and familial hemiplegic migraine, and to suggest that similar pathogenic mechanisms may underlie these two disorders.

This retrospective study evaluates the morbidity and outcome of cystectomy and urinary diversion in octogenarians with invasive bladder cancer. Records of all patients older than 80 years who underwent cystectomy during the last 10 years were analyzed retrospectively. Among 565 cystectomies, 11(< 2%) patients were identified and evaluated for intraoperative and postoperative complications and mortality post surgery. The median age was 82 years. One female and ten male patients were selected. Eight patients were hypertensive, three were diabetic, one had coronary artery disease, two had chronic lung disease and one had depression. Seven patients presented with hematuria, two had lower urinary tract symptoms and two presented with renal failure who were optimized for renal function. All patients had ileal conduit as the form of urinary diversion. Simultaneous urethrectomy was done in two patients. Median surgical time was 5 h. Median hospital stay after surgery was 10 days. Four patients had pneumonitis and one patient developed hemiplegia, but all patients were eventually discharged. One patient expired due to stent septicemia within one month after discharge. Follow-up ranged from four months to five years. Three patients expired three years after surgery-one due to disease recurrence and the other two due to unrelated cause. One patient was lost to follow-up and six patients are doing well. Our results support the use of cystectomy in octogenarians with invasive bladder cancer, which has acceptable morbidity and mortality, and offers the best chance for sustained disease-free quality survival.
