Nonmotor Symptoms of Parkinson’s Disease
Parkinson’s disease is generally thought of first and foremost as a disorder of motor control. The cardinal signs of PD are all motor defects, which generally respond favorably to dopaminergic stimulation. While the most obvious pathological change in PD is degeneration of pigmented neurons in the substantia nigra, many other neuronal pathways not involved in motor function (such as the noradre...
متن کاملNonmotor Symptoms of Parkinson's Disease
Nonmotor symptoms occur commonly in Parkinson's disease (PD) patients and are frequently under-recognized and undertreated. Symptoms include sleep abnormalities, fatigue, autonomic disturbances, mood disorders and cognitive dysfunction. Early recognition and treatment of nonmotor symptoms in PD is critical to providing optimal management. A new screening questionnaire and the revised Unified PD...
متن کاملNonmotor Symptoms in Patients with PARK2 Mutations
Decreased (123)I-meta-iodobenzylguanidine (MIBG) uptake in MIBG myocardial scintigraphy, olfactory dysfunction, and rapid eye movement (REM) sleep behavior disorder (RBD) are considered useful early indicators of Parkinson disease. We investigated whether patients with PARK2 mutations exhibited myocardial sympathetic abnormalities using MIBG scintigraphy, olfactory dysfunction using the Sniffin...
متن کاملNonmotor symptoms in patients with Parkinson disease
Parkinson disease (PD) is usually accompanied by numerous nonmotor symptoms (NMS), such as neuropsychiatric symptoms, sleep disorders, autonomic dysfunctions, and sensory disturbances. However, it is not clear that the factors influencing the occurrence of NMS and its sequence with motor symptoms (MS).We conducted comprehensive assessments of NMS by using 13 scales in 1119 PD patients.A total o...
متن کاملDopamine effects on identified rat vagal motoneurons.
Catecholaminergic neurons of the A2 area play a prominent role in brain stem vagal circuits. It is not clear, however, whether these neurons are noradrenergic or adrenergic, i.e., display tyrosine hydroxylase (TH) and dopamine-beta-hydroxylase (DbetaH) immunoreactivity (-IR) or dopaminergic (i.e., TH- but not DbetaH-IR). Our aims were to investigate whether a subpopulation of neurons in the A2 ...
