Short-term motor memory in Korsakoff patients

Perceptual and Motor Skills
L S Cermak, B Uhly

Abstract

10 amnesic alcoholic Korsakoff patients were compared with 10 chronic alcoholics for their ability to retain a simple motor movement over either a 10- or 20-sec. interval. During this interval the opportunity for rehearsal was minimized by having the patients engage in either a verbal or a motor distractor task. Under both conditions the Korsakoff patients were impaired relative to the control subjects, with very little difference between the two types of interference. It was concluded that Korsakoff patients have a short-term motor retention deficit that cannot be explained simply as an inability to mediate the task verbally.

COVID-19

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Sexual Dimorphism in Neurodegeneration

There exist sex differences in neurodevelopmental and neurodegenerative disorders. For instance, multiple sclerosis is more common in women, whereas Parkinson’s disease is more common in men. Here is the latest research on sexual dimorphism in neurodegeneration
