Pseudoparkinsonism: drug-induced parkinsonism (rigidity, bradykinesia, tremor, masked facies, shuffling gait, stooped posture, sialorrhoea, and seborrhoea; greater risk in the elderly). [2] Although Parkinson's disease is primarily a disease of the nigrostriatal pathway and not the extrapyramidal system, loss of dopaminergic neurons in the ...

A violently ill patient with neck stiffness during the Texas meningitis epidemic of 1911 and 1912. Neck stiffness, stiff neck and nuchal rigidity are terms often used interchangeably to describe the medical condition when one experiences discomfort or pain when trying to turn, move, or flex the neck.
Rigidity Resistance to externally imposed ("passive") joint movements, such as when a doctor flexes a patient's arm at the elbow joint. [ 9 ] It does not depend on imposed speed and can be elicited at very low speeds of passive movement in both directions.
Rigidity is a severe state of hypertonia where muscle resistance occurs throughout the entire range of motion of the affected joint independent of velocity. It is frequently associated with lesions of the basal ganglia. Individuals with rigidity present with stiffness, decreased range of motion and loss of motor control.
Hypokinetic movement disorders fall into one of four subcategories: akinesia (lack of movement), hypokinesia (reduced amplitude of movements), bradykinesia (slow movement), and rigidity. In primary movement disorders, the abnormal movement is the primary manifestation of the disorder.
Meningitis is an infection that causes the thin layers of the meninges that surround the brain and spinal cord to become inflamed, explains Dr. Rodrigo Hasbun, an infectious diseases professor at ...
Multiple system atrophy (MSA) is a rare neurodegenerative disorder [1] characterized by tremors, slow movement, muscle rigidity, postural instability (collectively known as parkinsonism), autonomic dysfunction and ataxia.
