OBJECTIVES: To explore the efficacy of Chinese herbal formula compared with donepezil 5 mg/day in patients with mild Alzheimer’s disease (AD). METHODS: Patients with mild AD meeting the criteria were randomized into Chinese herbal formula Yishen Huazhuo decoction (YHD) group and donepezil hydrochloride (DH) group during the 24-week trial. The outcomes were measured by ADAS-cog, […]

Wilsgaard, Tom,
Engstad, Torgeir A.
Background: Progressive neurodegeneration in Alzheimer’s disease (AD) induces cognitive deterioration, and there is controversy regarding the optimal treatment strategy in early AD. Stimulation therapy, including physical exercise and cholinesterase inhibitors are both reported to postpone cognitive deterioration in separate studies. We aimed to study the effect of stimulation therapy and the additional effect of donepezil […]

Souvenaid aims to improve synapse formation and function. An earlier study in patients with Alzheimer’s disease (AD) showed that Souvenaid increased memory performance after 12 weeks in drug-naïve patients with mild AD. The Souvenir II study was a 24-week, randomized, controlled, double-blind, parallel-group, multi-country trial to confirm and extend previous findings in drug-naïve patients with […]
Effect of B vitamins and lowering homocysteine on cognitive impairment in patients with previous stroke or transient ischemic attack: a prespecified secondary analysis of a randomized, placebo-controlled trial and meta-analysis

Background and Purpose: High plasma total homocysteine (tHcy) has been associated with cognitive impairment but lowering tHcy with B-vitamins has produced equivocal results. We aimed to determine whether B-vitamin supplementation would reduce tHcy and the incidence of new cognitive impairment among individuals with stroke or transient ischemic attack≥6 months previously.; Methods: A total of 8164 […]

Objective: We investigated induction of α-secretase A disintegrin and metalloprotease 10 (ADAM10) by the synthetic retinoid acitretin (Neotigason; Actavis, München-Riem, Germany) in patients with mild to moderate Alzheimer disease (AD) via measurement of CSF content of α-secretase-derived amyloid precursor protein (APPs-α).; Methods: Twenty-one patients clinically diagnosed with mild to moderate AD received acitretin (30 mg […]
Memantine for patients with Parkinson’s disease dementia or dementia with Lewy bodies: a randomised, double-blind, placebo-controlled trial

Jones, Roy
Background: Previous studies have suggested that patients with Lewy-body-related dementias might benefit from treatment with the N-methyl D-aspartate receptor antagonist memantine, but further data are needed. Therefore, the efficacy and safety of memantine were investigated in patients with mild to moderate Parkinson’s disease dementia (PDD) or dementia with Lewy bodies (DLB).; Methods: Patients (≥50 years […]
Designing a trial to evaluate potential treatments for apathy in dementia: the apathy in dementia methylphenidate trial (ADMET)

Rosenberg, Paul B.,
Herrmann, Nathan,
Bachman, David,
Mintzer, Jacobo E.
Background: Research on efficacious treatments for apathy in Alzheimer disease has been hindered by a lack of consensus diagnosis, difficulties in measurement, and studies with small sample sizes.; Methods: In designing the Apathy in Dementia Methylphenidate Trial (ADMET), a trial to evaluate the efficacy and safety of methylphenidate for the treatment of apathy in Alzheimer […]

Sensitivity to psychotropic medications presents a therapeutic challenge when treating neuropsychiatric symptoms in patients with dementia with Lewy bodies (DLB). We compared under randomized, double-blinded conditions the tolerability and efficacy of citalopram and risperidone in the treatment of behavioral and psychotic symptoms in patients with DLB and Alzheimer disease (AD). Thirty-one participants with DLB and […]
