The existence of cognitive disorders in autoimmune myasthenia is still debated. Chinese researchers have investigated this question using a battery of tests:
- 41 patients with a generalized form of myasthenia participated in a study that also included a control group of 45 people matched for gender, age and education level,
- the protocol consisted of neuropsychological tests, neurometabolite studies and functional brain imaging,
- the results point to global cognitive impairment, particularly in visuo-spatial function, language and memory, with parallel dysfunction in the prefrontal region and the left thalamus,
Although not devoid of methodological bias, this work sheds new light on this issue.
