Subthreshold depression in patients with Parkinson's disease and dementia: clinical and demographic correlates

Background About 40% of the patients with Parkinson's disease (PD) have depressive symptoms, either major depression (MD) or subthreshold depression. Depression was found to be associated with age and age at onset of PD, female gender, more severe parkinsonism, in particular with left-sided and akinetic-ligid symptoms, more functional impairment and cognitive impairment

Cortical Serotonin 1A Receptor Levels Are Associated with Depression in Patients with Dementia with Lewy Bodies and Parkinson's Disease Dementia

BACKGROUND: Serotonin 1A receptors (5-HT(1A)) have not been studied in dementia with Lewy bodies (DLB) or Parkinson's disease dementia (PDD) patients with depression. AIM: To examine 5-HT(1A) in DLB and PDD postmortem in relation to depression. METHODS: [(3)H]8-hydroxy-2-dipropylaminotetralin binding to 5-HT(1A) was determined in temporal cortex (Brodmann areas, BA20 and BA36) from 10 DLB patients, 17 PDD patients and 9 controls. RESULTS: 5-HT(1A) density was significantly higher in BA36 in combined DLB/PDD patients with depression, but was unaltered in BA20. CONCLUSION: Higher BA36 5-HT(1A) density in PDD and DLB patients than in control is dependent on whether the patient had experienced depression during life, not DLB/PDD diagnosis. A 5-HT(1A) antagonist adjuvant may improve treatment of depression in dementia
