This is the first study that focuses on insomnia in stroke patients. A subgroup of 277 patients from a consecutive series of 486 stroke patients aged 55-85 years was subjected to a comprehensive psychiatric evaluation 3-4 months after ischemic stroke. Of 277 patients, 56.7% reported any insomnia complaint and 37.5% fulfilled the DSM-IV criteria of insomnia. In 38.6%, insomnia complaint/insomnia had already been present prior to the stroke and in 18.1%, it was a consequence of the stroke. Independent correlates of any insomnia complaint/insomnia were anxiety (Zung Anxiety Scale) and the use of psychotropic drug. Independent correlates of poststroke-onset insomnia complaint/insomnia were disability after stroke (Barthel Index), dementia, anxiety and use of psychotropic drug. Insomnia should be taken into consideration in treating and rehabilitating stroke patients.

The evolution of subjective sleep and sleep electroencephalogram (EEG) after hemispheric stroke have been rarely studied and the relationship of sleep variables to stroke outcome is essentially unknown. We studied 27 patients with first hemispheric ischaemic stroke and no sleep apnoea in the acute (1-8 days), subacute (9-35 days), and chronic phase (5-24 months) after stroke. Clinical assessment included estimated sleep time per 24 h (EST) and Epworth sleepiness score (ESS) before stroke, as well as EST, ESS and clinical outcome after stroke. Sleep EEG data from stroke patients were compared with data from 11 hospitalized controls and published norms. Changes in EST (>2 h, 38% of patients) and ESS (>3 points, 26%) were frequent but correlated poorly with sleep EEG changes. In the chronic phase no significant differences in sleep EEG between controls and patients were found. High sleep efficiency and low wakefulness after sleep onset in the acute phase were associated with a good long-term outcome. These two sleep EEG variables improved significantly from the acute to the subacute and chronic phase. In conclusion, hemispheric strokes can cause insomnia, hypersomnia or changes in sleep needs but only rarely persisting sleep EEG abnormalities. High sleep EEG continuity in the acute phase of stroke heralds a good clinical outcome.

We assessed the prevalence and associations of symptoms of insomnia in patients with acute ischemic stroke, and evaluated whether mianserin as a sedative antidepressant is beneficial in the treatment of poststroke insomnia. One hundred consecutively hospitalized patients were randomized to receive 60 mg/day of mianserin (n = 51) or placebo for 1 year in a double-blind trial with a 6-month follow-up after the therapy. Symptoms of insomnia were assessed with the three insomnia-related items of the Hamilton Depression Scale; patients were defined as insomniacs if any of these items was positive. Complaints of insomnia occurred in 68% of patients on admission, and in 49% at 18 months, and they were as frequent in all subgroups of patients. From 2 months, symptoms of insomnia were associated independently with depression. Living alone before stroke (at 0 and 2 months) and age (at 12 months) were other independent predictors of insomnia. The rate of recovery as evaluated by the insomnia score was more rapid in patients on mianserin than in those on placebo. At 2 months, the scores were significantly different favoring mianserin treatment (1.3 vs. 0.8, p = 0.02). We conclude that insomnia is a common complaint after ischemic stroke. Mianserin had a beneficial influence on the recovery from symptoms of insomnia, even though the intensity of poststroke depression was low.

Sleep-disordered breathing (SDB) and sleep-wake disturbances (SWD) are frequent in stroke patients. They deserve attention, because they may significantly influence rehabilitation process and functional outcome. In addition, SDB may increase the risk of stroke recurrence. More than 50% of stroke patients have SDB, mostly obstructive sleep apnea (OSA). In some patients, stroke recovery is accompanied by an improvement of SDB. The treatment of choice for OSA is continuous positive airway pressure. Oxygen, theophylline, and other forms of ventilation may be helpful in patients with other forms of SDB (eg, Cheyne-Stokes breathing). In at least 20% to 40% of stroke patients, SWD are present, mainly in form of increased sleep needs (hypersomnia), excessive daytime sleepiness, or insomnia. Depression, anxiety, SDB, stroke complications (eg, nocturia, dysphagia, and urinary or respiratory infections), and drugs may contribute to SWD and should be addressed first. In patients with SWD of primary neurologic origin, treatment with stimulants or dopaminergic drugs and hypnotics or sedating antidepressants, respectively, can be attempted.

My aim is to examine the relation between some sleep disorders and neurological diseases; to analyse their mutual interactions in order to achieve new practical data for clinical use. In the theoretical part I summarise some main points of sleep physiology concentrating on the associations of sleep regulation and neurological diseases. In my examinations, besides clinical methods, the most important tools used are sleep analyses performed by polysomnography and MESAM IV as well as brain imaging methods. To assess clinical state of my stroke patients I utilised NIH Stroke Scale. I found pathological sleep apnoea frequency in more than half of the patients in any type (bleeding/infarction) of acute stroke. In a prospective study, sleep apnoea parameters remain permanent during 3 months in the ischaemic group; on the other hand, sleep apnoea improves during follow up after brain haemorrhages. I showed pathological sleep apnoea frequency in myasthenia gravis among male patients without daytime respiration complaint. I looked for the link between the mechanism of the sleep disorder and the underlying organic lesion in two cases. In this analyses I took into account the function of the affected structure in sleep regulation. I found a basal forebrain tumour, affecting sleep regulating centres underlying severe insomnia and I suggest a neuro-vascular compression of the lateral preoptic area of the hypothalamus being the reason of sleep related painful erection, a parasomnia of unknown origin.

This is the first study that focuses on the effects of intradermal acupuncture on insomnia after stroke. We enrolled hospitalized stroke patients with insomnia and assigned them into a real intradermal acupuncture group (RA group) or a sham acupuncture group (SA group) by randomization. The RA group received intradermal acupuncture on shen-men (He-7) and nei-kuan (EH-6) for 2 days, and the SA group received sham acupuncture on the same points. The effectiveness was measured by the Morning Questionnaire (MQ), Insomnia Severity Index (ISI), and Athens Insomnia Scale (AIS). These scales were examined by an independent, blinded neurologist before, and 1 and 2 days after treatment, repeatedly. Thirty subjects (15 in the RA group and 15 in the SA group) were included in the final analysis. The RA group showed more improvement on insomnia than the SA group. Repeated measures analysis detected that there were significant between-subjects effects in the MQ, the ISI and the AIS. In conclusion, we suggest that intradermal acupuncture on shen-men and nei-kuan is a useful treatment for post stroke-onset insomnia.

The active role (participation) that patients with chronic conditions are able to achieve has increasingly been recognised as a measure for the effectiveness of prevention- and rehabilitation strategies. An empowerment scale is an especially effective instrument for measuring social participation, and was applied to stroke patients in neurological rehabilitation for the first time. 26 stroke survivors and 26 informal carers, who participated in self-help groups in Lower Austria, were surveyed. The mean age was 63.9 (+/- 10.4) (stroke survivors) and 61.9 (+/- 9.6) years (informal carers). The mean duration of disease was 7.3 (+/- 3.2) years and the mean length of self-help group participation approximately 4 years. Every other stroke survivor and every fifth informal carer had to give up their professional life because of the stroke. Financial burden, reduction of vacations and social activities was found for both groups. Informal carers more frequently reported an increased fear of a relapse and generally of the future. One third of the stroke survivors had insomnia, depression, and nervousness. Reduced mobility, memory impairment, and increased sensitivity to temperature-changes were seen as the largest burdens. In spite of the large overlap in many domains of empowerment- and quality-of-life measures, empowerment measures also seem to reflect aspects of social participation. Therefore, measures of empowerment should be included in long-term outcome measurements following stroke.

More than 50% of stroke patients have sleep-disordered breathing (SDB), mostly in the form of obstructive sleep apnea (OSA). SDB represents both a risk factor and a consequence of stroke. The presence of SDB has been linked with poorer long-term outcome and increased long-term stroke mortality. Continuous positive airway presure is the treatment of choice for OSA. Oxygen and other forms of ventilation may be helpful in other (e.g., central) forms of SDB. SDB can improve spontaneously after stroke. About 20 to 40% of stroke patients have sleep-wake disorders (SWD), mostly in form of insomnia, excessive daytime sleepiness/fatigue, or hypersomnia (increased sleep needs). Depression, anxiety, SDB, stroke complications, and medications may contribute to SWD and should be addressed first therapeutically. Brain damage per se, often at thalamic or brainstem level, can be also a cause of persisting SWD. In these patients, hypnotics, dopeminergic agents, and stimulants (e.g., modafinil) can be attempted.

The study investigates the relative crash involvement risk associated with diagnosed medical conditions, subjective symptoms and the use of some medicines based on self-report questionnaires from 4448 crash-involved drivers. Whereas many previous studies of medical conditions and crash risk have focussed exclusively on elderly drivers, this study included drivers of all ages. Relative risk for each health condition was estimated by comparing drivers with and without the condition, regarding the odds of being at fault for the crash. Statistical significance was tested by a logistic regression analysis for each condition with crash culpability as the dependent variable. Relative risks were expressed as odds ratios (OR) adjusted for age and annual driving distance. The analyses identified the following significant risk factors: non-medicated diabetes (OR=3.08), a history of myocardial infarction (OR=1.77), using glasses when driving (OR=1.26), myopia (OR=1.22), sleep onset insomnia (OR=1.87), frequent tiredness (OR=1.36), anxiety (OR=3.15), feeling depressed (OR=2.43) and taking antidepressants (OR=1.70). In addition, there was a relatively large and nearly significant relative risk for drivers who had suffered a stroke (OR=1.93). For some additional conditions the crude odds ratios were significant, but failed to reach significance after correction for age and annual driving distance.

Western medicine was introduced to Taiwan in 1865 when Dr. James L. Maxwell, a missionary doctor of the English Presbyterian Church, established a hospital in nowadays Tainan. The period of the missionary medicine lasted for over 30 years until Japanese took over. During this period, however, official records of diseases in Taiwan that were based on Western medicine were scanty or not available. Fortunately, port surgeons stationing respectively in Tamsui and Kelung in the north and in Takow and Taiwan-fu in the south reported semi-annually diseases seen in the ports, foreign communities and missionary hospitals that they volunteered to work. The diseases reported by port surgeons were either cases or summary of cases with classification and statistics. Their medical reports covered from 1871 to 1900. The data show that neurological diseases and/or disorders in the late 19th century Taiwan were uncommon, comprising only 2-3% of total diseases. The data further show that common neurological diseases were leprosy, opium smoking, syphilitic dementia (GPI), paralysis, hysteria, neuralgia, epilepsy, mania, sciatica, meningitis and ataxia. Stroke was uncommon while Parkinson's disease and Alzheimer's disease were not mentioned, indicating that neurological diseases related to old age and neurodegeneration were not yet a threat to health. Similarly, headache, insomnia, anxiety and depression, hallmark of functional disorders of the modern society, were also not mentioned, suggesting that these disorders were indeed rare or did not cause sufficient concern for patients to seek help from doctors of Western medicine.
