Piracetam for dementia or cognitive impairment

The Cochrane Database of Systematic Reviews
L Flicker, G Grimley Evans


To determine the clinical efficacy of piracetam for the features of dementia or cognitive impairment, classified according to the major subtypes of dementia: vascular, Alzheimer's disease or mixed vascular and Alzheimer's disease, or unclassified dementia, or cognitive impairment not fulfilling the criteria for dementia. The trials were identified from a search of the Specialized Register of the Cochrane Dementia and Cognitive Improvement Group on 10 November 2000 using the term spiracetam, nootropic and 2-Oxo-1-pyrrolidine. In addition the pharmaceutical company responsible for marketing most of the piracetam worldwide, UCB Pharma, provided a comprehensive list of abstracts, which included many unpublished studies. As many of these unpublished, placebo-controlled studies will be reviewed as possible. All unconfounded trials specified as randomized in which treatment with piracetam was administered for more than a day and compared with placebo in patients with dementia of Alzheimer type, vascular dementia,or mixed vascular and Alzheimer's disease, or unclassified dementia, or cognitive impairment not fulfilling the criteria for dementia. Data were extracted independently by two reviewers. Each study was independently verified a...Continue Reading

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Bone Marrow Neoplasms

Bone Marrow Neoplasms are cancers that occur in the bone marrow. Discover the latest research on Bone Marrow Neoplasms here.

IGA Glomerulonephritis

IgA glomerulonephritis is a chronic form of glomerulonephritis characterized by deposits of predominantly Iimmunoglobin A in the mesangial area. Discover the latest research on IgA glomerulonephritis here.

Cryogenic Electron Microscopy

Cryogenic electron microscopy (Cryo-EM) allows the determination of biological macromolecules and their assemblies at a near-atomic resolution. Here is the latest research.

STING Receptor Agonists

Stimulator of IFN genes (STING) are a group of transmembrane proteins that are involved in the induction of type I interferon that is important in the innate immune response. The stimulation of STING has been an active area of research in the treatment of cancer and infectious diseases. Here is the latest research on STING receptor agonists.

LRRK2 & Immunity During Infection

Mutations in the LRRK2 gene are a risk-factor for developing Parkinson’s disease. However, LRRK2 has been shown to function as a central regulator of vesicular trafficking, infection, immunity, and inflammation. Here is the latest research on the role of this kinase on immunity during infection.

Antiphospholipid Syndrome

Antiphospholipid syndrome or antiphospholipid antibody syndrome (APS or APLS), is an autoimmune, hypercoagulable state caused by the presence of antibodies directed against phospholipids.

Meningococcal Myelitis

Meningococcal myelitis is characterized by inflammation and myelin damage to the meninges and spinal cord. Discover the latest research on meningococcal myelitis here.

Alzheimer's Disease: MS4A

Variants within membrane-spanning 4-domains subfamily A (MS4A) gene cluster have recently been implicated in Alzheimer's disease by recent genome-wide association studies. Here is the latest research.
