Periodic limb movement disorder is characterized by recurrent episodes of frequent limb movements while sleeping. It mostly happens in the lower parts of the body like the toes, ankles, knees and hips. It can also, in some cases, appear in the upper extremities of the body. These movements can lead the patient to wake up, and if so, sleep ...
Parkinsonism is a clinical syndrome characterized by tremor, bradykinesia (slowed movements), rigidity, and postural instability. [ 1 ][ 2 ] Both hypokinetic (bradykinesia and akinesia) as well as hyperkinetic (cogwheel rigidity and tremors at rest) features are displayed by Parkinsonism. [ 3 ] These are the four motor symptoms found in ...
Parkinsonian gait (or festinating gait, from Latin festinare [to hurry]) is the type of gait exhibited by patients with Parkinson's disease (PD). [ 2 ] It is often described by people with Parkinson's as feeling like being stuck in place, when initiating a step or turning, and can increase the risk of falling. [ 3 ]
Parkinson's disease (PD), or simply Parkinson's, is a neurodegenerative disease of mainly the central nervous system that affects both the motor and non-motor systems of the body. The symptoms usually emerge slowly, and, as the disease progresses, non-motor symptoms become more common. Usual symptoms include tremors, slowness of movement ...
Parkinson-plus syndromes (PPS) are a group of neurodegenerative [1] diseases featuring the classical features of Parkinson's disease (tremor, rigidity, akinesia / bradykinesia, and postural instability) with additional features that distinguish them from simple idiopathic Parkinson's disease (PD). Parkinson-plus syndromes are either inherited ...
Psychiatry. Rhythmic movement disorder (RMD) is a neurological disorder characterized by repetitive movements of large muscle groups immediately before and during sleep often involving the head and neck. It was independently described first in 1905 by Zappert as jactatio capitis nocturna and by Cruchet as rhythmie du sommeil. [ 1 ]
Movement disorders are clinical syndromes with either an excess of movement or a paucity of voluntary and involuntary movements, unrelated to weakness or spasticity. [ 1 ] Movement disorders present with extrapyramidal symptoms and are caused by basal ganglia disease. [ 2 ] Movement disorders are conventionally divided into two major categories ...
Frequency. 5 per 100,000 people. Multiple system atrophy (MSA) is a rare neurodegenerative disorder [ 1 ] characterized by tremors, slow movement, muscle rigidity, and postural instability (collectively known as parkinsonism), autonomic dysfunction and ataxia. This is caused by progressive degeneration of neurons in several parts of the brain ...
