Akinetic crisis and withdrawal syndromes: guideline “Parkinson’s disease” of the German Society of Neurology

Monika Pötter-NergerMatthias Löhle German Parkinson‘s Guideline Group

The akinetic crisis is a well-known, rare, potentially life-threatening condition in Parkinson’s disease with subacute worsening of akinesia, rigidity, fever, impaired consciousness, accompanying vegetative symptoms and transient dopa-resistance. The akinetic crisis was historically supposed to be a “withdrawal syndrome” in the sense of discontinuation of dopaminergic medication. Recently, other “withdrawal syndromes” as the specific “dopamine agonist withdrawal syndrome” or “deep brain stimulation withdrawal syndrome” have been described as emergency situations with specific subacute symptom constellations. All three conditions require immediate start of the adequate therapy to improve the prognosis. Here, the diagnostic criteria and treatment options of these three acute, severely disabling syndromes will be reported along the current guidelines of the German Parkinson Guideline Group.
