Discordance Between Perceptions and Experience of Lumbar Puncture: A Prospective Study.

Background And Objectives: Novel diagnostic techniques and neurologic biomarkers have greatly expanded clinical indications for CSF studies. CSF is most commonly obtained via lumbar puncture (LP). Although it is generally believed that LPs are well tolerated, there is a lack of supportive data for this claim, and patients anticipate LP to be painful.

A Young Adult with White Matter Changes and Recurrent Stroke Symptoms.

White matter changes on MRI can be a diagnostic puzzle as a large group of inflammatory, autoimmune, infectious, and neoplastic conditions can present in this way. An otherwise healthy 36-year-old male presented with his second episode of unilateral weakness, the first episode occurring five years previously. He did not have sensory or cerebellar symptoms with the current or previous episode.

Interval timing and midfrontal delta oscillations are impaired in Parkinson's disease patients with freezing of gait.

Gait abnormalities and cognitive dysfunction are common in patients with Parkinson's disease (PD) and get worse with disease progression. Recent evidence has suggested a strong relationship between gait abnormalities and cognitive dysfunction in PD patients and impaired cognitive control could be one of the causes for abnormal gait patterns. However, the pathophysiological mechanisms of cognitive dysfunction in PD patients with gait problems are unclear.

Color discrimination errors associate with axial motor impairments in Parkinson's disease.

Background: Visual function deficits are more common in imbalance-predominant compared to tremor-predominant PD suggesting a pathophysiological role of impaired visual functions in axial motor impairments.

Objective: To investigate the relationship between changes in color discrimination and motor impairments in PD while accounting for cognitive or other confounder factors.

Methods: PD subjects (n=49, age 66.

Huntington's Disease-Update on Treatments.

Huntington's disease (HD) is an autosomal dominantly inherited neurodegenerative disease characterized by progressive motor, behavioral, and cognitive decline, ending in death. Despite the discovery of the underlying genetic mutation more than 20 years ago, treatment remains focused on symptomatic management. Chorea, the most recognizable symptom, responds to medication that reduces dopaminergic neurotransmission.
