Here are 10 of the top types of offenders. Indeed, the brain can grow new brain cells and reshape their connections throughout life.Most people are familiar with at least some of the things that can impair memory, including alcohol and drug abuse, heavy cigarette smoking, head injuries, stroke, sleep deprivation, severe stress, vitamin B12 deficiency, and illnesses such as Alzheimer's disease and depression.But what many people don't realize is that many commonly prescribed drugs also can interfere with memory. ![]() But scientists now know that memory loss as you get older is by no means inevitable. for AARP: Are you having trouble remembering things? One of these meds may be the problem.For a long time doctors dismissed forgetfulness and mental confusion as a normal part of aging. ![]() Specificity of intersubunit general anesthetic-binding sites in the transmembrane domain of the human α1β3γ2 γ-aminobutyric acid type A (GABAA) receptor. GABA-activated ligand gated ion channels: medicinal chemistry and molecular biology. Lack of direct involvement of a diazepam long-term treatment in the occurrence of irreversible cognitive impairment: a pre-clinical approach. Midazolam disrupts fear memory reconsolidation. Benzodiazepines and antidepressants: effects on cognitive and functional decline in Alzheimer’s disease and Lewy body dementia. G., Jaramillo-Jimenez A., Oesterhus R., Santacruz J. ![]() The GABAa agonist gaboxadol is known to bind to GABAa receptors containing the α4 and ბ subunits (Zanettini et al., 2016 Sente et al., 2022).īorda M. Another anxioselective compound, Ocinaplon (pyrazolopyrimidine) has affinity to all DS isoforms, with higher affinity to α1 compared to α5 (Lippa et al., 2005). The anxioselective drug Alpidem (Non-BZD) has affinity to α1, α2, and α3 isoforms, but not the α5 isoform (Sieghart and Savic, 2018). The anxioselective compounds Bretazenil (partial agonist), and Abecarnil (Non-BZD) have affinity to both DS and DI GABAa receptors (Mehta and Shank, 1995 Pym et al., 2005). GABAa receptor isoforms containing α4 and α6 subunits are categorized as DI (Diazepam Insensitive) (Sigel and Ernst, 2018). Classical BZDs have high affinity to DS (Diazepam Sensitive) isoforms of GABAa receptors which include α1, α2, α3, and α5 subunits (Sigel and Ernst, 2018). Understanding these mechanisms will allow for the development of alternative treatments and potentially allow BZDs to be used as a novel tool to study Alzheimer's disease.Īlzheimer’s disease GABAA anterograde amnesia benzodiazepines fear conditioning sex differences.īenzodiazepines, non-benzodiazepines, and other anxioselective compounds show affinity for specific isoforms of GABAa receptors. This review aims to inspire new research directions, as there is a gap in knowledge in understanding the cellular and molecular mechanisms behind BZD-induced amnesia. Additionally, the relationship between BZD use and cognitive decline related to Alzheimer's disease is addressed, as there is a lack of consensus on whether these drugs are involved in inducing or accelerating pathological cognitive deficits. In this review we discuss, behavioral paradigms, sex differences and hormonal influences affecting BZD-induced amnesia, molecular manipulations, including the knockout of GABAa receptor subunits, and regional studies utilizing lesion and microinjection techniques targeted to the hippocampus and amygdala. ![]() However, these drugs come with the detrimental side effect of anterograde amnesia, or the inability to form new memories. Benzodiazepines (BZDs) are anxiolytic drugs that act on GABAa receptors and are used to treat anxiety disorders.
