Significant loss of neurons in the pedunculopontine nucleus pars compacta (PPNc), a putative cholinergic nucleus involved in modulating somatic motor activities, has been demonstrated in progressive supranuclear palsy (PSP) and Parkinson's disease but not in Alzheimer's disease. A morphometric study of this nucleus was performed in two cases of PSP and in a cohort of cases of Parkinson's disease, Alzheimer's disease, senile dementia of Alzheimer type (SDAT), and age-matched controls. In PSP a significant 60% neuronal loss in PPNc was associated with neurofibrillary tangles in 40 to 64% of the remaining neurons. In Parkinson's disease there was a significant decrease in cell numbers and density by 53 and 51%, respectively, with Lewy bodies involving 6 to 39% of all neurons. In Alzheimer's disease and SDAT, large neurons were reduced by 29 and 33.8%, respectively, with tangles in 9 to 38% of the remaining cells. The selective affection of this putative cholinergic nucleus in PSP and Parkinson's disease appears to be related to motor dysfunctions in these disorders.

D010300	Parkinson Disease	A progressive, degenerative neurologic disease characterized by a TREMOR that is maximal at rest, retropulsion (i.e. a tendency to fall backwards), rigidity, stooped posture, slowness of voluntary movements, and a masklike facial expression. Pathologic features include loss of melanin containing neurons in the substantia nigra and other pigmented nuclei of the brainstem. LEWY BODIES are present in the substantia nigra and locus coeruleus but may also be found in a related condition (LEWY BODY DISEASE, DIFFUSE) characterized by dementia in combination with varying degrees of parkinsonism.

D011149	Pons	The front part of the hindbrain (RHOMBENCEPHALON) that lies between the MEDULLA and the midbrain (MESENCEPHALON) ventral to the cerebellum. It is composed of two parts, the dorsal and the ventral. The pons serves as a relay station for neural pathways between the CEREBELLUM to the CEREBRUM.
