Alprazolam, diazepam, and lorazepam are familiar names to anyone who has ever suffered from severe anxiety or insomnia. These anxiolytics and sleeping pills offer short-term relief, but their long-term impact on the brain is particularly significant.
Studies show that prolonged benzodiazepine use can double the risk of developing Alzheimer’s disease. These drugs interfere with neurotransmitters, alter sleep patterns (which are essential for memory consolidation), and create strong physical and psychological dependence. In fact, more than 40% of regular users report difficulty concentrating and a loss of mental energy.
5. Amphetamines
Often prescribed for attention deficit hyperactivity disorder (ADHD), amphetamines temporarily stimulate concentration by artificially increasing dopamine levels in the brain.Health
However, high doses and continuous administration eventually exhaust the nervous system. Research indicates that this prolonged use can lead to lasting brain damage, affecting not only memory, but also motivation and overall cognitive performance, not to mention the risks of chronic irritability and depression.
6. Tricyclic antidepressants
Although they are among the oldest treatments for depression, amitriptyline and nortriptyline are still used. While they act on serotonin reuptake to improve mood, they also possess strong anticholinergic properties.
Like the Parkinson’s disease medications mentioned above, these antidepressants inhibit acetylcholine. Elderly patients are particularly sensitive to this and may experience accelerated cognitive decline, characterized by severe confusion, frequent memory lapses, and an inability to concentrate.
