Unfortunately, every year prescription drugs are responsible for more than 100,000 deaths and lead to over 1.5 cases of hospitalized people who experienced severe side-effects.

Every prescription drug carries some risk, but one of the most common side-effects is memory loss.

3 Types of medications that cause memory loss:


Sleeping pills are notorious for their potential to cause memory loss.

Ambien, the popular drug was claimed to be “the amnesia drug” because those who use it experience sleep walking, night terrors, hallucinations and sleep driving.

It is found that sleeping pills can cause a state similar to being drunk or being in a coma.

So, people who use these pills do not experience the restorative sleep the brain needs in order to maintain and repair itself. However, there are many other ways to fall asleep than using sleeping pills.


Statin drugs are popular cholesterol-lowering drugs which are one of the worst groups of medications for your brain. They lead to memory loss, which should be listed on the label as a serious side-effect.

One-quarter of your brain is composed of cholesterol which is important for learning, memory and fast thinking. So, these cholesterol-lowering medications seriously affect the brain health.

Every drug that starts with “anti” including antidepressants, antihistamines, antipsychotics, antispasmodics, antibiotics or antihypertensive will affect your acetylcholine level.

The primary neurotransmitter involved in learning and memory is acetylcholine. When there is low-level of acetylcholine, the following conditions may occur delirium, mental confusion, blurred vision, hallucinations, memory loss, and dementia.
