Beware 20 Medications That Cause Memory Loss


Prescription medicine leads to more than 100,000 deaths annually and affects additional 1.5 million people to sustain serious side effects resulting in patient hospitalization.

Negative medicine reaction is listed as the fourth chief cause of death in the US. Each prescription drug poses some health risks, memory loss being one of them.

The Top 3 Types of Drugs That Lead to Memory Loss

Beware 20 Medications That Cause Memory Loss

There are three groups of medications identified as potential causes of memory loss and other cognitive problems, so if you are on any medicine, it’s very likely that it belongs to one of the following groups:

The “Anti” Drugs

Any drug starting with “anti,” like antidepressants, antipsychotics, antihistamines, antibiotics, antispasmodics, or antihypertensives, will probably influence your acetylcholine levels.

The principal neurotransmitter, Acetylcholine, takes part in both memory and learning. Low acetycholine levels can produce symptoms that are very similar to dementia as well as memory loss, mental confusion, blurred vision, hallucinations and delirium.

Sleeping Pills

Prescription sleeping pills are infamous for their influence on memory loss.

Some even refer to the popular drug Ambien as “the amnesia drug.” Ambien users are prone to sleep walking, night terrors, sleep driving and hallucinations.

These medications have shown a capacity to produce states similar to coma or being passed out drunk while depriving the brain of the recuperative sleep it needs. There are far better ways to get rid of insomnia!

Statin Drugs

Statin medications, which decrease your cholesterol levels, are presumably the most harmful group of drugs for your brain. It is now required that memory loss is listed as a side effect on their label.

Cholesterol occupies one quarter of your brain and is essential for memory, learning, and fast thinking. It’s no wonder that cholesterol-lowering pills produce adverse effects on the brain.
