The decrease was greater in the hippocampus and frontal cortex sildenafil joint pain. 4-HIAA concentrations in the CSF are lower in depressed patients with PD than in the others , and imipramine-like drugs, which are inhibitors of serotonin uptake, have significant antidepressant activity in patients with PD. No difference between patients with and without dementia was observed.
It seems, however, that, like the noradrenergic deficiency, the serotoninergic deficit is more likely to be implicated in depressive states in patients with PD. A role in the depression observed in patients with PD is also substantiated. The same analysis can be made for the ascending serotoninergic neurons.
The central serotoninergic deficiency may be implicated in cognitive processes. Judging from neuronal loss in the raphe nuclei and decreased serotonin concentrations in the striatopallidal complex and in certain cortical areas , these neurons are partially destroyed in PD. In accordance with the noradrenergic hypothesis of depression, tricyclic antidepressants that are potent noradrenaline uptake blockers have been shown to be efficacious in treatment of depressed patients with PD (Strang, 1972).

In rare instances no cause for the increased red cell production can be found , as a diagnosis sildenafil joint pain of exclusion. A paraneoplastic polycythemia (associated with ectopic production of erythropoietin) is observed in certain kidney tumors, hepatomas, uterine myomas, cerebellar hemangiomas, and other rare tumors. Rarely, familial or congenital polycythemias are observed. In the Chuvash polycythemia , a mutation of the VHL protein leads to impaired interaction with HIF-1, which results in defective oxygen sensing. In some but not all families, a gain-of-function truncation of the erythropoietic receptor is responsible.
Some nonmalignant kidney lesions (e.g., polycystic kidney disease) also stimulate the production of erythropoietin.
