We determined the frequency of dropped head syndrome in Parkinson's disease (PD) in Japan and evaluated its clinical correlates. A total of 252 consecutive patients with PD who visited our hospital were studied. Dropped head syndrome was found in 15 patients (6.0%) (3 men, 12 women; mean age at onset of PD, 62.8 +/- 11.5 years). The interval before emergence of dropped head after disease onset was 5.4 +/- 4.3 years (-0.5 to 15 years). The Hoehn-Yahr score at the on stage was 3.2 +/- 0.7; at the off stage 3.5 +/- 0.8. Of those 15 patients, 8 had major symptoms of rigidity and akinesia. In 2 patients, administration of a dopamine agonist appeared to evoke dropped head syndrome. An increase in and/or the addition of antiparkinsonian drugs alleviated head drop in 4 patients and reduced head drop in 7 patients. Any medication was not effective for 4 patients. Dropped head syndrome in PD is not rare in Japan. It is more often observed in women and is associated with patients who primarily suffer rigidity and akinesia. Dropped head syndrome in these patients appears to be produced by disproportionate tonus of the neck muscles. It is modulated by antiparkinsonian drugs and is considered to be a type of dystonia.

Our results show that the prevalence of subclinical CAD in ischemic stroke patients was high, and that a quarter of them had high-risk CAD. Age, diabetes, stroke, and male sex were independent predictors of high-risk CAD.

BackgroundTriptans are effective for immediate relief of episodic cluster headache (CH) but do not reduce the frequency of attacks. Intravenous bolus injection of corticosteroids like methylprednisolone (MP) has been reported to decrease the frequency of CH attacks. We validated the prophylactic efficacy of MP pulse therapy by monitoring CH recurrence over several years following treatment of six consecutive male patients (mean age: 38.8 years, range: 26–54 years) afflicted by frequent (often daily) CH attacks.FindingsTotal MP dose per infusion was 250–500 mg for five patients and 125 mg for the sixth (a diabetic). High-dose MP was administered for 2 or 3 consecutive days in hospital for the first two patients treated. The next four patients received a single bolus injection at presentation, and in some cases a second injection days later at an outpatient clinic. The first two cases treated were also prescribed daily oral prednisolone for at most 6 months while the latter four cases were not. The frequency of CH attacks was markedly reduced in all patients, with intervals between attacks ranging from 4 to 23 months. We noted no apparent adverse events following MP administration.ConclusionsHigh-dose MP therapy reduced CH attack frequency and improved patient quality of life.
