There is evidence that migraine is a risk factor for stroke but little is known about this association in elderly people. Furthermore, non-migrainous headache (NMH) has received little attention despite being the most frequently reported type of headache. Late-life migraine and NMH were examined as candidate risk factors for stroke in a community-dwelling elderly sample over a 12-year follow-up. ⋯ This study is one of the first to suggest that late-life NMH rather than migraine could be an independent risk factor for stroke and a warning sign. The incidence of stroke in elderly migrainers, seldom reported, is particularly low.

Aneurysmal subarachnoid hemorrhage (SAH) survivors often complain of fatigue, which is disabling. Fatigue is also a common symptom of pituitary dysfunction (PD), in particular in patients with growth hormone deficiency (GHD). A possible association between fatigue after SAH and long-term pituitary deficiency in SAH survivors has not yet been established. ⋯ Fatigue is a common symptom amongst SAH survivors. WFNS is a usable clinical determinant of fatigue in SAH survivors. Neither PD nor GHD has a significant effect on long-term fatigue after SAH.

Observational Study
Effect of natalizumab on brain atrophy and disability progression in multiple sclerosis patients over 5 years.
The long-term benefit of natalizumab on brain atrophy progression in multiple sclerosis (MS) patients is unknown. Our aim was to investigate its effect over 5 years. ⋯ In line with previous reports, MS patients with longer and continuous use of natalizumab had fewer relapses and remained stable in their disability status. No difference in lesion burden accumulation or brain atrophy development was found in relation to the duration of natalizumab use. PML occurred in 2.5% of patients in this small sample cohort. Given the increased risk of PML and uncertain benefit of prolonged natalizumab use on clinical and MRI outcomes of disease progression found in this study, a careful risk-benefit therapeutic assessment is mandatory.

Dual antiplatelet therapy (DAPT) with aspirin and clopidogrel for 90 days was recommended as the secondary prevention of minor ischaemic strokes or transient ischaemic attacks (TIAs) in 2014. However, whether the duration of 90 days is optimal for each patient remains unclear. Therefore, the efficacy and safety of short-term (≤3 months) and prolonged (≥1 year) DAPT after stroke or TIA were assessed via a systematic review and meta-analysis. ⋯ Short-term DAPT appears to be superior to prolonged DAPT. However, the difference in efficacy outcome needs to be carefully explained and confirmed by further well-designed randomized controlled trials.
