Informations about the disease

Clinical Comment

Parkinson syndrome is a generic term with different etiologies (idiopathic, non-idiopathic Parkinson syndrome). Parkinson syndromes are defined by akinesia and one of the variably expressed cardinal symptoms rigor, resting tremor, postural instability. Optional accompanying symptoms are sensory symptoms (dysesthesias, pain, hyposmia), autonomic symptoms (disturbances of blood pressure and/or temperature regulation, bladder/bowel function and sexual function), psychological symptoms (depression), sleep disturbances, cognitive symptoms (frontal disturbances, dementia). The vast majority of patients with Parkinson syndrome with the typical motor signs suffer from idiopathic Parkinson disease (with Lewy- body pathology), which is slowly progressive. Parkinson diseases that occur before the age of 40 are called "early onset", those that begin before the age of 21 are called "juvenile". The multitude of genetic (co-)causes of Parkinson syndrome is taken into account with an extensive panel, all known modes of inheritance are represented. However, monogenic Parkinson disease accounts for only 5-10% of the total Parkinson spectrum. The DNA diagnostic yield is also low in the juvenile Parkinson subgroup with up to 15% of detected pathogenic sequence alterations. Inconspicuous genetic findings do not imply a definite exclusion of the suspected neurological diagnosis.
