FDA Approves Lecanemab, a New Alzheimer ’s Drug
On Jan. 6, the U.S. Food and Drug Administration (FDA) approved a new drug to treat Alzheimer’s disease in its early stages. Lecanemab, which will be available under the name Leqembi, can slow the cognitive decline associated with Alzheimer’s disease by 27%, according to data submitted to the FDA by the drug’s developers, Eisai and Biogen. It’s only the second medication to show any improvement in neurodegeneration, a key criterion in the FDA’s consideration for approval. “For a long time, this is what we have been looking for,” says Dr. Sam Gandy, professor of neurology and psychi...

Cholinesterase inhibitors for vascular dementia and other vascular cognitive impairments: a network meta-analysis
CONCLUSIONS: We found moderate- to high-certainty evidence that donepezil 5 mg, donepezil 10 mg, and galantamine have a slight beneficial effect on cognition in people with VCI, although the size of the change is unlikely to be clinically important. Donepezil 10 mg and galantamine 16 to 24 mg are probably associated with more adverse events than placebo. The evidence for rivastigmine was less certain. The data suggest that donepezil 10 mg has the greatest effect on cognition, but at the cost of adverse effects. The effect is modest, but in the absence of any other treatments, people living with VCI may still wish to consid...

Donepezil down-regulates propionylation, 2-hydroxyisobutyrylation, butyrylation, succinylation, and crotonylation in the brain of bilateral common carotid artery occlusion-induced vascular dementia rats.
In this study, we evaluated the effects of donepezil on VaD, and investigated the underlying molecular mechanisms of action. VaD was established by ligation of the bilateral common carotid artery occlusion (BCCAO). Executive function was tested by the Morris Water Maze (MWM) test and the attentional set shifting task (ASST). Our results showed that donepezil improved executive dysfunction and cognitive flexibility in BCCAO rats. In addition, we showed that donepezil treatment decreased the level of Aβ1-42 in BCCAO rats by enzyme-linked immunosorbent assay. Posttranslational modifications (PTMs) are known to be critical me...

Pharmacotherapy for Vascular Cognitive Impairment
AbstractVascular cognitive impairment (VCI) is the second most common type of dementia after Alzheimer ’s disease (AD). Stroke and cardiovascular risk factors have been linked to both AD and VCI and potentially can affect cognitive function in mid and later life. Various pharmacological agents, including donepezil, galantamine, and memantine, approved for the treatment of AD have shown modest cogni tive benefits in patients with vascular dementia (VaD). However, their functional and global benefits have been inconsistent. Donepezil has shown some cognitive benefit in patients with VaD only, and galantamine has shown some...

Probable Nootropic-induced Psychiatric Adverse Effects: A Series of Four Cases
Conclusion Healthcare providers in general, and specifically those in the mental health and substance abuse fields, should keep in mind that nootropic use is an under recognized and evolving problem. Nootropic use should be considered in cases where there are sudden or unexplained exacerbations of psychiatric symptoms in patients who have been stable and medication adherent. It is also important to remember that most nootropics are not detected on standard drug toxicology screening tests. We have very little clinical information on how nootropics may interact with psychotropics (or other medications) and potentially cause ...
