Filter by:Background: Approximately 40% of patients with Parkinson's disease (PD) have cognitive impairments. There is a lack of consensus as to the extent to which psychiatric symptoms, depression, age at disease onset, disease duration, and medication is related to the type and severity of cognitive impairment. This discrepancy can in part be caused by the lack of distinction between patients with different motor symptoms and disease severity. Objective: To identify the extent to which psychiatric symptoms, depression, age at disease onset, disease duration, and medication is related to the severity and type of cognitive dysfunction in patients with idiopathic PD categorized according to motor symptoms and disease severity. Methods: the population of patients with PD in the old county of Aarhus is described on the background of medical records, and stratified in accordance to age, sex and cardinal symptoms. Through proportional allocation a sample of a minimum of 50 patients with PD is drawn from the population. The patients and 30 healthy matched controls will undergo comprehensive neuropsychological assessment including tests of language, memory, executive function, and visuospatial function. Furthermore, all participants will be screened for depression (Geriatric Depression Scale) and psychiatric symptoms (Neuropsychiatric Inventory and Symptom Checklist). The patients will be categorized in accordance with their motor symptoms via cluster analysis for the purpose of analyzing the effect of psychiatric symptoms, depression, and age of disease onset, disease duration, and medication on cognition.
GSK239512 is being developed for the treatment of symptoms of cognitive impairment in many diseases. GSK239512 is a drug that binds to the Histamine 3 receptor (a protein) in the brain (receptor occupancy). This study will use the technique of positron emission tomography (PET) as an imaging tool to highlight areas of the brain that GSK239512 has penetrated, and subsequently bound to receptors, after receiving an oral dose of the drug. It will also look at the rate the drug dissociates from the receptors in the brain. Results from the study will provide information on doses of the drug to be given in further studies.
The purpose of this study is to determine the acute effects of the nicotinic receptor allosteric modulator galantamine (0, 4 and 8 mg) on neurocognitive function in schizophrenic smokers (n=20) versus schizophrenic nonsmokers (n=10) in an outpatient human laboratory setting.
This study will determine the effectiveness of a peer support system in increasing physical activity and effecting health behavior change in people with serious mental illnesses.
Our hypothesis is that adding midazolam and/or fentanyl to propofol sedation for elective outpatient colonoscopy increases cognitive impairment at hospital discharge without improving intraoperative conditions or reducing intraoperative side-effects. 200 healthy patients aged 18 years or older will be randomised to receive propofol or propofol plus midazolam and/or fentanyl. Cognitive impairment will be tested at hospital discharge using Cogstate computerised testing software.
The purpose of this project is to evaluate an exercise and health promotion program for older adults with mild memory loss. The study will investigate the efficacy of a memory-enhanced exercise and health promotion program to determine whether it is more effective than a social walking program in delaying further memory decline, improving mood and physical function, and enhancing quality of life.
The purpose of this study is to find out if insulin, when administered as a "nasal spray" into the nasal passages, improves memory in adults with mild cognitive impairment (MCI) or Alzheimer's disease.
The purpose of this study is to find out if different doses of Investigational Drug are safe, tolerable, and if they have an effect on Mild Cognitive Impairment (MCI).
The primary objective is to compare mild cognitive impairment in the AL-208 group with the placebo group at 14 + - 3 days after CABG surgery
The purpose of this study is to determine the effects and cost-effectiveness of a Diagnostic Observation Center for PsychoGeriatric patients (DOC-PG). Our main hypothesis is that DOC-PG has added value compared with usual care regarding Health Related Quality of Life (HRQoL).
