Abstract:
19 middle-aged patients with myasthenia gravis (MG) and 10 age-matched controls underwent overnight polysomnography and neuropsychological testing, in order to assess the frequency, degree, type and risk factors of sleep apneas in MG and to show their influence on sleep profile and neuropsychological variables. We observed in 60% of the myasthenics, low grade central type of sleep apneas and hypopneas with resulting oxygen desaturations, occasionally occurring during REM-sleep without influence on sleep profile and vigilance but resulting in significant memory impairment. The only found risk factor for the development of sleep apneas was age.

Chemical Synapses
Because chemical synapses depend on the release of neurotransmitter molecules from synaptic vesicles to pass on their signal, there is an approximately one millisecond delay between when the axon potential reaches the presynaptic terminal and when the neurotransmitter leads to opening of postsynaptic ion channels. Additionally, this signaling is...

Musculoskeletal disorders
Musculoskeletal disorders involve injuries and conditions affecting the skeletal muscles and associated connective tissues. These disorders can arise from acute biomechanical stresses or chronic overuse and can occur across different age groups. Common injuries include sprains, fractures, and muscular strains, often resulting from...
