Cerebral and cognitive modifications in retired professional soccer players: TC-FOOT protocol, a transverse analytical study.

Introduction: Soccer is the most popular sport in the world. This contact sport carries the risk of exposure to repeated head impacts in the form of subconcussions, defined as minimal brain injuries following head impact, with no symptom of concussion. While it has been suggested that exposure to repetitive subconcussive events can result in long-term neurophysiological modifications, and the later development of chronic traumatic encephalopathy, the consequences of these repeated impacts remain controversial and largely unexplored in the context of soccer players.

Lyme neuroborreliosis and dementia.

Introduction: Descriptions of Lyme disease and dementia are rare.

Objective: To describe patients with dementia and a positive "intrathecal anti-Borrelia antibody index" (AI), specific for neuroborreliosis.

Methods: Among 1,594 patients seen for dementia, we prospectively identified and studied 20 patients (1.

Cognitive Dysfunction and Dementia in Primary Sjögren's Syndrome.

Background. Primary Sjögren's syndrome (PSS) is a frequent systemic autoimmune disease. In this study, we aimed to explore the cognitive impairment and the correlations with brain MRI.

White matter atrophy and cognitive dysfunctions in neuromyelitis optica.

Neuromyelitis optica (NMO) is an inflammatory disease of central nervous system characterized by optic neuritis and longitudinally extensive acute transverse myelitis. NMO patients have cognitive dysfunctions but other clinical symptoms of brain origin are rare. In the present study, we aimed to investigate cognitive functions and brain volume in NMO.
