Rivastigmine improves dual-task gait velocity in patients with Alzheimer's disease.

Background: Gait impairments are common in patients with Alzheimer's disease. Cholinesterase inhibitors are used to treat the symptoms of patients with Alzheimer's disease, but they have not been shown to reduce the severity of Alzheimer's disease-related gait disorders.

Methods: This was a prospective, single-arm, open-label, non-randomized study.

White matter lesions and cognitive impairment may be related to recovery from unilateral spatial neglect after stroke.

Background: Unilateral spatial neglect (USN) is frequently found in ischemic stroke patients. Because USN is related to poor functional outcomes, evaluating recovery from USN after stroke is critical.

Methods: Patients with acute ischemic stroke with lesions in the right cerebral hemisphere on MRI and exhibiting left USN were administered the Behavior Inattention Test (BIT) at 1 and 3weeks after admission.

Influence of barometric pressure in patients with migraine headache.

Objective: Barometric pressure has been reported as a triggering and exacerbating factor in migraine headaches, although there are few reports concerning the association of weather change and migraine headache. The relationship between barometric pressure changes and migraine headaches was prospectively examined.

Methods: A total of 28 migraine patients who lived within 10 km of the Utsunomiya Local Meteorological Observatory kept a headache diary throughout the year.

[A 62-year-old woman presenting with progressive nonfluent aphasia, apraxia of eyelid opening, supranuclear gaze palsy, and asymmetric rigidity].

A 62-year-old woman presented with difficulty in speaking and difficulty in opening her eyes. A neurological examination revealed progressive nonfluent aphasia (PNFA), apraxia of eyelid opening, supranuclear vertical gaze palsy, and mild asymmetric rigidity. The diagnosis was difficult to establish because of unusual clinical features, and progressive supranuclear palsy (PSP) was considered.

Evaluation of olfaction in patients with migraine using an odour stick identification test.

Aims: Peculiar characteristics of migraine headaches include the arousal of olfaction during the attacks and osmophobia. We performed an olfactory test to evaluate the association between olfaction and migraines.

Methods: We evaluated olfactory dysfunction in 80 migraine patients (31 experienced migraines with aura (MWA), 49 migraine without aura (MWOA)) and 30 healthy controls.

Prevalence of typical migraine aura without headache in Japanese ophthalmology clinics.

The aim of this study was to investigate the prevalence and characteristics of typical aura without headache (TAWH) in Japan. We distributed a self-report questionnaire comprising seven items. Of 1914 cases, the number of patients who provided valid answers was 1063.

[Case of subdural empyema caused by Porphyromonas and Fusobacterium identified by 16S ribosomal RNA gene sequence analysis].

A 24-year-old woman presented subdural empyema developing from sinusitis caused by Porphyromonas and Fusobacterium infection. She experienced fever and progressive headache with gradually worsening symptoms. Neurological examination revealed drowsiness and neck stiffness.
