RBD is a sleep disorder characterized by the loss of normal skeletal muscle atonia during REM sleep and is associated with prominent motor activity and vivid dreaming. [6] [2] These dreams often involve screaming, shouting, laughing, crying, arm flailing, kicking, punching, choking, and jumping out of bed.
They can also cause a neurological disorder known as tick paralysis. [33] Mites. Ear mites are microscopic members of the species Otodectes cynotis. Symptoms include itching, inflammation, and black debris in the ear. [34] Cheyletiellosis is a mild pruritic skin disease caused by Cheyletiella yasguri. Humans can be transiently infected. [34]
A dog with degenerative myelopathy often stands with its legs close together and may not correct an unusual foot position due to a lack of conscious proprioception. Canine degenerative myelopathy, also known as chronic degenerative radiculomyelopathy, is an incurable, progressive disease of the canine spinal cord that is similar in many ways to amyotrophic lateral sclerosis (ALS).
Sleep paralysis occurs when your mind is awake, but your body can’t move, Xue Ming, a sleep expert and professor of neurology at the Rutgers New Jersey Medical School, tells me. You can ...
This is a list of major and frequently observed neurological disorders (e.g., Alzheimer's disease), symptoms (e.g., back pain), signs (e.g., aphasia) and syndromes (e.g., Aicardi syndrome). There is disagreement over the definitions and criteria used to delineate various disorders and whether some of these conditions should be classified as ...
Narcolepsy is a chronic neurological disorder that impairs the ability to regulate sleep–wake cycles, and specifically impacts REM (rapid eye movement) sleep. [1] The pentad symptoms of narcolepsy include excessive daytime sleepiness (EDS), sleep-related hallucinations, sleep paralysis, disturbed nocturnal sleep (DNS), and cataplexy. [1]
According to the activation-synthesis hypothesis proposed by Robert McCarley and Allan Hobson in 1975–1977, control over REM sleep involves pathways of "REM-on" and "REM-off" neurons in the brain stem. REM-on neurons are primarily cholinergic (i.e., involve acetylcholine); REM-off neurons activate serotonin and noradrenaline, which among ...
Rule out sleep disorders causing sleep instability; Rule out medical disorders or treatments associated with sleep instability; Confirm presence of NREM parasomnias in other family members and during the patient's childhood; Determine the timing of the events; Determine the morphology of the events.
