Cognitive reserve involves decision making and is associated with left parietal and hippocampal hypertrophy in neurodegeneration.

Cognitive reserve is the ability to actively cope with brain deterioration and delay cognitive decline in neurodegenerative diseases. It operates by optimizing performance through differential recruitment of brain networks or alternative cognitive strategies. We investigated cognitive reserve using Huntington's disease (HD) as a genetic model of neurodegeneration to compare premanifest HD, manifest HD, and controls.

Emotion expression through spoken language in Huntington disease.

Patients with Huntington's disease suffer from disturbances in the perception of emotions; they do not correctly read the body, vocal and facial expressions of others. With regard to the expression of emotions, it has been shown that they are impaired in expressing emotions through face but up until now, little research has been conducted about their ability to express emotions through spoken language. To better understand emotion production in both voice and language in Huntington's Disease (HD), we tested 115 individuals: 68 patients (HD), 22 participants carrying the mutant HD gene without any motor symptoms (pre-manifest HD), and 25 controls in a single-centre prospective observational follow-up study.

Predicting clinical scores in Huntington's disease: a lightweight speech test.

Objectives: Using brief samples of speech recordings, we aimed at predicting, through machine learning, the clinical performance in Huntington's Disease (HD), an inherited Neurodegenerative disease (NDD).

Methods: We collected and analyzed 126 samples of audio recordings of both forward and backward counting from 103 Huntington's disease gene carriers [87 manifest and 16 premanifest; mean age 50.6 (SD 11.

Improving language evaluation in neurological disorders: The French Core Assessment of Language Processing (CALAP).

Aphasia is a devastating brain disorder, detrimental for medical care and social interaction. The early diagnosis of language disorders and accurate identification of patient-specific deficits are crucial for patients' care, as aphasia rehabilitation is more effective when focused on patient-specific language deficits. We developed the Core Assessment of Language Processing (CALAP), a new scale combining screening and detailed evaluation to rapidly diagnose and identify patient-specific language deficits.
