Introduction: In this study we explored brainstem reflex excitability changes, blink reflex recovery cycles (BRRCs), and masseter inhibitory reflexes (MIRs) in patients with amyotrophic lateral sclerosis (ALS). Methods: Fourteen ALS patients and 14 healthy control subjects were recruited. The BRRC was examined at interstimulus intervals (ISIs) of 100, 200, 300, 400, 500, and 600 ms. The latencies and durations of silent period 1 (SP1) and silent period 2 (SP2) of the MIR were measured. Results: Decreased R2 area suppression was prominent in the ALS group at ISIs of 200, 300, and 400 ms (P < 0.02), whereas no significant differences between groups at 100, 500, and 600 ms ISIs (P > 0.05) were observed. SP2 duration was significantly prolonged in the ALS group compared with controls (P = 0.01). Conclusions: Brainstem inhibitory and excitatory interneuronal activity is altered in ALS, possibly brought about by physiological and morphological changes at the cortical or bulbar levels.

To identify any structural differences in macular choroidal thickness in migraine patients and compare them with that of control subjects by using spectral domain optic coherence tomography (SD-OCT). In this prospective study, choroidal thicknesses of 32 migraine patients during migraine attack-free period and 32 age-and sex-matched healthy subjects were measured using SD-OCT. All patients underwent a complete ophthalmic examination before the measurements. The migraine patients were classified into the migraine with aura group or the migraine without aura group. Migraine severity was assessed by visual analog scale (VAS), migraine disability questionnaire (Migraine Disability Assessment Score (MIDAS), and Wong-Baker faces pain rating scale. Thirty eyes of 32 subjects (31 female and 1 male) in the migraine group and 32 eyes of 32 subjects (31 female and 1 male) in control group were evaluated. In the study group, 16 patients suffered migraine without aura (MWA) and 16 patients were diagnosed as migraine with aura (MA). The mean subfoveal choroidal thickness (SFCT) was 353.3 +/- 66.5 mu m in the control group versus 304.3 +/- 72.9 mu m and 276.1 +/- 61.4 mu m in MWA and MA groups, respectively. The difference in SFCT between the migraine patients and the controls was significant (p < 0.001). Additionally, a moderate correlation was found between SFCT and the VAS score and W baker score (r = 0.48, p = 0.008 and r = 0.43, p = 0.02, respectively). The choroidal thickness was found to decrease significantly not only in migraine patients with aura but also in those without aura during the attack-free period.

WOS: 000373736400014, PubMed ID: 25936385, Objective: To determine the frequency and severity as well as the diagnosis and treatment of overactive bladder problems in patients with multiple sclerosis (MS) followed up at five centers in Turkey. Design: Survey study. Setting: Outpatient tertiary clinics of physical medicine and rehabilitation and neurology. Participants: Consecutive MS patients scheduled for outpatient follow-up (n=309). Intervention: MS patients were asked to complete a questionnaire regarding the frequency and severity, as well as the diagnosis and treatment of their overactive bladder problems. Results: The mean age +/- SD was 39.3 +/- 10.6 years. Urinary urgency was the most common urinary symptom (62%), followed by frequency (50.4%), urge incontinence (44.7%) and nocturia (33%). Residual urine volume was measured using a portable ultrasound instrument in 13.3% of the patients and by catheterization in 16.2% of them. Urodynamic investigations and urinary tract ultrasound were performed on 26.5% and 35.3% of the patients, respectively. Anticholinergic medications were prescribed for 27.5% of the patients. Intermittent catheterization and indwelling catheterization were used on 8.1% and 1.9% of the patients, respectively. The overactive bladder symptom score (OABSS) was significantly higher in patients who had had residual urine measurement (P
