Complete resolution of restless legs syndrome following ischemic stroke of the right middle cerebral artery.

Stroke-related restless legs syndrome (sRLS) is an emerging clinical entity, with a clear relationship between stroke and the occurrence of restless legs syndrome (RLS). Dopamine dysregulation has been observed in sRLS of the lenticulostriate region with increased dopamine precursor and decreased dopamine transporter. The aim of this work is to explore an original case of regressive RLS following stroke.

The electroretinography to identify biomarkers of idiopathic hypersomnia and narcolepsy type 1.

Hypersomnia spectrum disorders are underdiagnosed and poorly treated due to their heterogeneity and absence of biomarkers. The electroretinography has been proposed as a proxy of central dysfunction and has proved to be valuable to differentiate certain psychiatric disorders. Hypersomnolence is a shared core feature in central hypersomnia and psychiatric disorders.

Episodic memory improvement in illiterate adults attending late-life education irrespective of low socioeconomic status: insights from the PROAME study.

Unlabelled: The majority of people with dementia live in low or middle-income countries (LMICs) where resources that play a crucial role in brain health, such as quality education, are still not widely available. In Brazil, illiteracy remains a prevalent issue, especially in communities with lower socioeconomic status (SES). The PROAME study set out to explore basic education in illiterate adults as a means to improve cognitive reserve.

Restless legs syndrome in the dominant Parkinson's side related to subthalamic deep-brain stimulation.

Background: Restless legs syndrome (RLS) has an increased estimated prevalence in patients with Parkinson's disease (PS). RLS frequently mimics symptoms intrinsic to PD, such as motor restlessness, contributing to making its diagnosis challenging in this population. We report the case of a patient with new-onset RLS following subthalamic deep-brain stimulation (DBS-STN).

Images: Sleep-related painful erection with concomitant hypnic headache.

Unlabelled: Sleep-related painful erection (SRPE) is a parasomnia defined by the repetition of painful erections during rapid eye movement (REM) sleep. Hypnic headache (HH) is a primary headache occurring exclusively at night, often during REM sleep. We report the observation of a 33-year-old man with simultaneous SRPE and HH.
