Purpose: Early rehabilitation is widely recommended for acute-stroke patients. We tested the hypothesis that the functional prognosis of stroke patients receiving daily early rehabilitation in a clinical practice setting is generally better than that of patients receiving rehabilitation only on weekdays.

Materials And Methods: We analyzed hospitalized patients who experienced either cerebral infarctions or cerebral hemorrhages and subsequently underwent rehabilitation at our hospital between October 2010 and September 2014.

Objective: Early rehabilitation for acute stroke patients is widely recommended. We tested the hypothesis that daily intervention by speech therapists promotes safe oral intake of patients with acute stroke.

Methods: We analyzed hospitalized patients who experienced cerebral infarction and cerebral hemorrhage and who underwent rehabilitation between October 2010 and September 2014 at our hospital.

Objective: While acetylcholinesterase inhibitors, such as donepezil, galantamine, and rivastig-mine, are beneficial in treating behavioral symptoms of patients with Alzheimer's disease (AD), their dose-limiting effects include gastrointestinal disturbances, such as nausea, vomiting, and diarrhea. We aimed to predict the occurrence of these gastrointestinal disturbances with rivastigmine therapy for optimal drug choice and improved compliance.

Materials And Methods: Thirty patients with mild-to-moderate AD (scores 10-22 on the MiniMental State Examination) were administered a rivastigmine 18 mg patch with domperidone 30 mg (RWD) and without domperidone (RWOD; n = 15 each) for 20 weeks.

Clinical trials have shown the benefits of acetylcholinesterase inhibitors, such as donepezil and galantamine, and an N-methyl-D-aspartate receptor antagonist, memantine, in patients with Alzheimer's disease (AD). However, little is known regarding the effects of switching from donepezil 5 mg/day to galantamine 16 or 24 mg/day, or regarding the effects of adding memantine to established therapy compared with increasing the dose of donepezil. This report discusses two studies conducted to evaluate treatment with galantamine and memantine with respect to cognitive benefits and caregiver evaluations in patients with AD receiving donepezil 5 mg/day for more than 6 months.

Previous studies of brain single-photon emission tomography (SPECT) showed changes of regional cerebral blood flow (rCBF) in migraineurs during prodromes or headache attacks. Little is known about how successful medication of migraine prevention can reflect rCBF in migraineurs. We highlighted alternation of brain SPECT findings in a migraineur with aura before and after prophylactic treatment with lomerizine, a calcium channel blocker.

Background: Oxidative stress plays a role in the pathogenesis of neuronal death. Serum levels of urate or lipid were associated with the incidence of Parkinson's disease (PD).

Objective: We compared urate, paraoxonase-1 (PON1), iron, ferritin and lipid in sera of 119 PD patients and 120 healthy controls matched by age, sex and body mass index.

Background: Clinicoradiological variability of vertebrobasilar dolichoectasia (VBD) is known. Little is known about cardiovascular disease (CVD) risk and neuroradiological profiles of asymptomatic VBD.

Methods: A total of 7,345 adults (5,534 men and 1,811 women) underwent physical checkup (PC) and brain magnetic resonance (MR) studies between 2004 and 2007.

We examined whether pramipexole (PPX) can influence depressive scale in normal and mild depressive parkinsonian patients. In an open study of PPX as an add-on to L-dopa therapy or single administration, 36 nondemented outpatients with Parkinson's disease (PD) were entered first. All were in the stage II or III of Hoehn and Yahr scale (H&Y).

Cheiro-oral-pedal syndrome is characterized by specific sensory disturbance around the corner of the mouth, in the hand and in the foot on the same side. Lesions responsible for causing this syndrome vary. We report two cases of cheiro-oral-pedal syndrome due to midbrain and pontine hemorrhage, respectively.

We report a case of myasthenia gravis (MG) associated with autoimmune thrombocytopenic purpura (AITP) and autoimmune hemolytic anemia (AIHA), and after that gastric cancer appeared. A 51-year-old man began to suffer from fluctuated muscle weakness in 1985. Muscle weaknesses became exacerbated, and he was admitted to our hospital in 1989.

We report the case of a 64-year-old man with sudden onset of numbness in the right hand and foot. Neurological examinations were normal except for hypersthesia, and hyperalgesia of the right hand and foot. Brain MRI demonstrated a high signal intensity on T2-weighted image and a low signal intensity on T1-weighted image in the left tegmetum of the pons.
