What Are Some Diseases That Cause Memory Loss?

Memory loss can be a scary thing regardless of your age. But as one ages, he or she may see an improvement in memory function or a decline in memory function. You may notice these problems with Short Term Memory Loss – Having a hard time remembering the names of people you met yesterday? Or where did you put last night’s glass of water? Short-term memory loss is common among adults and has little to do with mental aging. There are many different types of memory (e.g., autobiographical memory, procedural memory), but we generally think of memory as the ability to recall information about people, places, and events. This is referred to as declarative memory.

Memory is not a single process but rather involves many different processes. It involves encoding (i.e., combining information with previous experiences), storing (i.e., retaining information over time), and retrieving (i.e., recalling information at a later time). Memory impairment can occur if one of these processes is disrupted (see ’causes’).

Memory loss is often associated with aging, but it is essential to remember that not all people experience memory decline as they grow older. Many people’s memories improve with age since they become more experienced over time and may develop more effective strategies for learning new things.

Memory loss may be mild or severe depending on its cause and progression. Mild symptoms include forgetting names or words and difficulty remembering recent events. 

What are the Causes for Memory Loss?

The following are the most standard causes of memory loss:

Alzheimer’s disease- Alzheimer’s disease is a brain disorder. This disorder causes a slow decline in memory, thinking, and reasoning skills. There are some treatments available to help minimize some symptoms of Alzheimer’s disease you can look for.

Thyroid problem- Both an overactive (hyperthyroidism) and underactive thyroid (hypothyroidism) can lead to forgetfulness and other thinking problems.

Vitamin B-12 deficiency- This can cause symptoms of confusion that are often mistaken for mental illness. It also can cause forgetfulness and problems with thinking and concentration.

Depression- People with this condition may have trouble focusing and concentrating and may experience forgetfulness.

There are many causes of confusion and memory loss, including:

  • Dementia
  • Medications
  • Depression and anxiety
  • Thyroid problems
  • Seizures

Diseases that Cause Memory Loss

Let’s discuss some brain disease that causes memory loss.

Alzheimer’s disease:

As it progresses, people with Alzheimer’s may forget how to do simple tasks. For example, brushing their teeth or combing their hair. This is the most common brain disease that causes memory loss.

Vascular dementia:

Vascular dementia symptoms can develop suddenly or gradually. Others have several strokes or smaller areas of damaged tissue.

Huntington’s disease:

Many people with Huntington’s disease have milder cases that are not diagnosed until later in life. Huntington’s disease is caused by an expansion of a section of DNA known as a CAG trinucleotide repeat. Some people with this condition have up to 35 CAG repeats; however, people typically develop symptoms only if they have more than 40 repeats. The loss of these neurons leads to uncontrolled movements, problems with mental abilities, and psychiatric.

Frontotemporal dementia:

The nerve cell loss leads to shrinking (atrophy) of your brain’s front and side areas. It’s not clear why this happens, but scientists think it’s related to deposits of abnormal proteins in your brain. The deposits cause your brain cells to malfunction and die. 

Several other Rare Brain Diseases can Cause Memory Loss:

Creutzfeldt-Jakob disease (CJD):

CJD is a rare brain disease that causes brain loss. CJD is characterized by rapidly progressive dementia, most commonly seen in those between the ages of 60 and 65 years old.

Alexander Disease:

These cells help keep the brain generally working by providing support and protection for the nerve cells (neurons) that transmit signals to and from the brain. When astrocytes are healthy, they are shaped like a star and are called star-shaped cells or astrocytes. However, in Alexander’s Disease, these cells do not function properly, which affects their shape and causes them to become clumped together. The clumping of these abnormal cells results in the buildup of a glial fibrillary acidic protein (GFAP) protein. Over time, this buildup can cause the affected areas of the brain to swell, which can lead to seizures and impair mental development.

What are some Prevention for this Disorder?

Here are some preventive measures for memory loss:

Get moving- It increases oxygen to your brain, which promotes brain health. It also relieves stress, improves memory and cognitive skills, and may reduce the risk of dementia. The benefits begin immediately, too. Even short 10-minute bursts of activity are helpful.

Adopt a healthy diet- Fish, nuts, fruits, vegetables, and grains provide nutrients that keep your brain healthy while keeping you full and energized. Antioxidants, such as vitamins E and C and beta carotene, have been found to help slow age-related memory loss and thinking problems (cognitive decline). Other nutrients that are beneficial for brain health include B vitamins (thiamin, riboflavin, niacin), vitamin D, iron, selenium, zinc, and essential fatty acids. If you’re concerned about specific nutrients or want guidance on supplements to take in addition to food sources, check with your doctor.

Get organized- Organization can help reduce stress and make it easier for you to find your keys and remember appointments. When you go to the grocery store, make a detailed list of what you need. And remember you need to stick with it to avoid impulse purchases.

Eat more fruits and vegetables- Fruits and vegetables contain antioxidants, which reduce inflammation in the body and help prevent damage to cells. (Antioxidants also may help protect against cancer.) Go for five to nine servings a day — the more colorful, the better. Try spinach or kale salad with berries, sliced carrots or tomatoes with dip; or steamed broccoli with lemon juice.


In conclusion, it can be helped with good habits, proper diet, and exercise. Make sure you get plenty of sleep, eat more fruits and vegetables, and stay active throughout the day to stop memory loss in its tracks before it can take control of your wellbeing.
