Effectiveness of an intervention in groups of family caregivers of dependent patients for their application in primary health centers. Study protocol
Background: Although Primary Health Care (PHC) Teams are used to deal with prevention and treatment of sanitary problems in adults with chronic diseases, they usually have a lack of experience in development of psychotherapeutic interventions. However, these interventions are the ones that achieve better results to reduce symptomatology and improve emotional state of caregivers.The study […]

Docosahexaenoic acid supplementation and cognitive decline in Alzheimer disease: a randomized trial
Context: Docosahexaenoic acid (DHA) is the most abundant long-chain polyunsaturated fatty acid in the brain. Epidemiological studies suggest that consumption of DHA is associated with a reduced incidence of Alzheimer disease. Animal studies demonstrate that oral intake of DHA reduces Alzheimer-like brain pathology.; Objective: To determine if supplementation with DHA slows cognitive and functional decline […]

Effectiveness of a specific care plan in patients with Alzheimer’s disease: cluster randomised trial (PLASA study)
Objective: To test the effectiveness of a comprehensive specific care plan in decreasing the rate of functional decline in patients with mild to moderate Alzheimer’s disease compared with usual care in memory clinics.; Design: Cluster randomised trial.; Setting: 50 memory clinics in France.; Participants: Patients with Alzheimer’s disease (mini-mental state examination score 12-26). 1131 patients […]

Persistence of the effects of Cerebrolysin on cognition and qEEG slowing in vascular dementia patients: results of a 3-month extension study
The maintenance of the effects of Cerebrolysin, a peptidergic compound with neurotrophic activity, on cognitive performance and qEEG activity was investigated through a 12-week, open-label extension of a 4-week, randomised, placebo-controlled pilot study. Thirty-three out of 41 patients with mild-to-moderate severe probable vascular dementia (VaD) according to NINDS-AIREN participating in the double-blind phase of the […]

Short-term effect of combined drug therapy and cognitive stimulation therapy on the cognitive function of Alzheimer’s disease
Background: Acetylcholinesterase inhibitors (i.e. donepezil) are known to benefit Alzheimer’s disease (AD) patients. However, the combined effects of acetylcholinesterase and cognitive stimulation therapy (CST) are still debated. The present study examined their combined effects on the progression of cognitive decline in AD.; Methods: The present study was a non-randomized controlled study and included two groups […]

EDUCA study: Psychometric properties of the Spanish version of the Zarit Caregiver Burden Scale
Objectives: The Zarit Caregiver Burden Scale, translated and validated into Spanish, is sensitive to the application of a Psychoeducational Intervention Program (PIP) for the prevention and reduction of burden in caregivers of Alzheimer’s disease (AD) patients (EDUCA study). The data obtained in EDUCA was used to reanalyse its psychometric properties and the cut-off points of […]

Clinical observation on effect of scalp electroacupuncture for mild cognitive impairment
Objective: To evaluate the therapeutic effect of scalp electroacupuncture for mild cognitive impairment (MCI) in the early stage.; Methods: Two hundred and thirty three MCI patients were randomly divided into three groups: the drug group, the scalp electroacupuncture group, and the syndrome differentiation group. For the scalp electroacupuncture group, the points of Baihui (DU 20), […]

The synergistic effect of acupuncture and computer-based cognitive training on post-stroke cognitive dysfunction: a study protocol for a randomized controlled trial of 2 × 2 factorial design
Background: Stroke is one of the most common causes of cognitive impairment. Up to 75% of stroke survivors may be considered to have cognitive impairment, which severely limit individual autonomy for successful reintegration into family, work and social life. The clinical efficacy of acupuncture with Baihui (DU20) and Shenting (DU24) in stroke and post-stroke cognitive […]

Effect of handball training on cognitive ability in elderly with mild cognitive impairment
The aim was to examine the effect of handball training on cognitive ability in elderly with mild cognitive impairment. A total of 60 elderly were randomly divided into training group (n=30) and control group (n=30). The mini-mental state examination (MMSE) score and abilities of daily living scale (ADL) score before, after 3-month, and after 6-month […]

Effects of memantine on clinical ratings, fluorodeoxyglucose positron emission tomography measurements, and cerebrospinal fluid assays in patients with moderate to severe Alzheimer dementia: a 24-week, randomized, clinical trial
Most experts consider that memantine has a symptomatic treatment, but clinical trials have not yet provided compelling evidence to support a disease-modifying effect. We investigate the effects of memantine on clinical ratings; fluorodeoxyglucose positron emission tomography (FDG-PET) measurements, which can monitor disease-modifying effect; and cerebrospinal fluid (CSF) assays in patients with moderate to severe probable […]
