入选标准
- •All participants must express that they are willing to take part in this study and adhere to the study procedures. They must also be native or fluent English speakers. It is important that participants are highly proficient in the English language as the verbal memory test will be in English. They must also have normal or corrected to normal vision as poor vision may interfere with visual memory testing. We will recruit both men and women.
- •We aim to recruit healthy participants who are 65 years or older. However, if we recruit a patient who is younger than this, we will attempt to find an age-matched healthy control. All patients participating in this study will either have a diagnosis of MCI or mild AD. Those with a diagnosis of AD or MCI will have been diagnosed by a general practitioner or a neurologist, according to established criteria (Albert et al., 2011; McKhann et al., 2011).
- •All participants will be capable to consent for themselves. Participants are deemed as capable of giving informed consent if they score above 11/30 in MoCA, and if the person taking consent deems the volunteer capable. MoCA is a conservative test and 11/30 on a MoCA corresponds to 20/30 on the mini mental state examination (MMSE) (Roalf et al., 2013), which is another commonly used diagnostic measure. We have extensive experience assessing capacity in this way and all participants will be reviewed by a consultant neurologist before administering any treatment.
- •Are the trial subjects under 18? no
- •Number of subjects for this age range: 0
- •F.1.2 Adults (18-64 years) no
- •F.1.2.1 Number of subjects for this age range 0
- •F.1.3 Elderly (>=65 years) yes
- •F.1.3.1 Number of subjects for this age range 90
排除标准
- •The participants must not have:
- •? clinically significant neurological or psychiatric diagnoses, other than MCI or mild AD in the patient group. This will be assessed by self-report and questionnaires during the screening visit.
- •? known posterior cortical atrophy (mainly relevant for MCI and AD, who will have had a brain scan as a part of the diagnostic procedure)
- •? clinically significant sleep problems in the past year
- •? an undiagnosed skin lesion. Participants will be asked about this.
- •? a known sensitivity to levodopa, ropinirole, benserazide, or domperidone
- •? known lactose intolerance, galactosemia or glucose/galactose malabsorption
- •? known galactose intolerance
- •? known Lapp lactase deficiency
- •? diagnosis of Huntington’s Chorea
- •? clinically significant intention tremor. This will be screened for by a trained investigator
- •? known prolactin-releasing pituitary tumour (prolactinoma)
- •? diagnosis of glaucoma
- •? a history of, or current, malignant melanoma
- •? diagnosed unstable diabetes (people with stable type 2 diabetes diet controlled diabetes may be recruited)
- •? severe endocrine, hepatic, renal, pulmonary, or cardiac disorder
- •? diagnosed electrolyte disturbances
- •? known peptic ulcers
- •? history of a heart-attack or prolongation of cardiac conduction intervals, or any other cardiac problems as taking domperidone increases risk of said problems. An ECG will be taken at the screening visit and heart-rate and blood pressure will be monitored before and after drug administration, as specified elsewhere in this protocol.
- •? current cancer treatment
- •? Body weight higher than 150 kilograms, as this puts participants at a highly elevated risk of having sleep apnea, which will interfere with sleep recordings. High body weight may also cause difficulty in the MR-scanner.
- •The participant must not be taking:
- •? dopaminergic medications
- •? noradrenergic, serotonergic, or anticholinergic medications started or changed within the past 3 months
- •? monoamine oxidase inhibitors (MAO-I), except if selective MAO-A or MAO-B inhibitors are given alone. MAO-A and MAO-B inhibitors given together are equivalent to non-selective MAO-inhibition and therefore volunteers taking both MAO-A and MAO-B will not be included in this study
- •? cholinesterase inhibitors, except if the participant has been on stable treatment (at least 3 months)
- •? antihypertensive (blood pressure) drugs containing reserpine
- •? ferrous sulphate on the day of testing
- •? opioids or sympathomimetics (e.g. amphetamines, epinephrine/adrenaline)
- •? diazepam or other benzodiasepines, unless none taken for prior 3 days or stable dose has been maintained for more than 3 months
- •? ketoconazole, erythromycin or CYP3A4 inhibitors (e.g. fluoconazole, voriconazole, clarithromycin, amiodarone, telithryomycin)
- •? antibiotics
- •? hormone replacement therapy
- •? anti-fungal agents (pentamidine)
- •? anti-malarial agents
- •? antihistaminics unless stable dose for 3 months or none for 3 days prior to testing sessions
- •? AIDS/HIV medications
- •? if a participant takes antacids or antisecretory agents they should not be taken at the same time as domperidone (but these participants can be included if the medication can be taken at a different time)
- •The participants will be asked to provide a list of medications they take, including alternative medication, and a clinician will verify that the participant is eligible for the study and that none of these medication interfere with co-beneldopa, ropinirole or domperidone. We will ask particip
