What causes memory loss and forgetfulness at a young age

Every time you ask your teen to do chores or homework, they may conveniently respond with how they “just forgot” to carry out your instructions. As they exhibit these signs of forgetfulness, life can become especially chaotic with the disorganization which ensues. Teens often have many responsibilities to juggle with their school work, extracurricular activities, chores, and of course, their social life. Details to consider is that your teen may not be intentionally forgetting – they could actually have physiological reasons or need a marijuana abuse program at an adolescent treatment center in Mississippi.

Hormones

With the surge of brand-new hormones, the brain gets overstimulated with emotions that are often difficult to control. As the brain continues to grow throughout adolescence, this development will affect functionality in different parts of the brain, including the prefrontal cortex. Focus, planning, memory, and the control of social behaviors can become hit or miss due to the growth happening in the brain. Forgetfulness becomes inevitable with the ongoing evolution which the brain experiences during adolescence.

Sleep Patterns

The bottom line is that teens need sleep. Eight to ten hours a night is the suggested recommendation of sleep that teens need during these crucial years of their development. Putting other activities at higher importance over sleep can make concentration and the ability to remember difficult to achieve. A rested teenager has a better chance of remembering than one who is sleep deprived.

Multi-tasking

Teens should stick to one task at a time because they can overload their brain with too much information and get stuck not doing anything at all. Too many instructions and too many activities in one day can overwhelm a teenager to the point that they forget what needs to be done altogether.

Health Conditions

Your teen may be suffering from a condition that affects their brain such as dyslexia, ADHD, depression, substance use disorder or problems with their thyroid. If you think that your teen is forgetting more than what’s normal of what you think they should, take them to their pediatrician and let the doctor know your concerns. By ignoring any issues your teen may be dealing with, they may not get the help they need to stop forgetting or remaining distracted.

Forgetfulness is a normal aspect in a teen’s life, but if you do your part to make sure your teen is thriving, you are also making sure they are exhibiting normal mental growth. Observe to see if your teen falls into any of these categories and help them to resolve their issues as necessary. This will be instrumental in limiting their forgetfulness and expanding their memory capabilities.

We've all been in a situation where we forget the name of the person we are meeting, the hilarious movie we’ve seen a million times or even just where we kept those pesky car keys again. We also often notice our grandparents and parents forgetting things we told them every now and then. To forget things is a natural part of being human. After all, we aren’t machines.

But when forgetting things at a young age of 20 or 30 becomes a pattern, then you might need to reconsider your overall health. Here are five medical reasons that could be responsible for forgetfulness at a young age:

1. Lack of sleep

Lack of adequate and restful sleep could easily lead to mood swings and anxiety, which in turn contribute to poor memory.

Sleep-deprived people are more likely to develop high blood pressure and diabetes, thus they may have constricted (narrowed) blood vessels. These narrowed blood vessels decrease proper blood flow to the brain. This limitation of blood flow could affect the ability of the brain to work properly.

A study conducted on mice claimed that sleep deprivation leads to more deposition of beta-amyloid (a protein) in the brain. The increased beta-amyloid deposits in the brain lead to a decrease in memory and thinking power.

2. Medications

Some medications that can affect the memory of a person even at a young age are anti-depressants (prescribed for migraine, depression), tranquillizers (prescribed for anxiety, depression and sleep disorders), anti-hypertensive drugs (prescribed for high blood pressure) and anticholinergics (prescribed in the case of pulmonary diseases, muscle spasms, gastrointestinal problems). 

They either cause sedation which may confuse the person or block the brain chemical messenger (acetylcholine) like in case of anticholinergics. Thus, the person could keep on forgetting things. 

The Food and Drug Administration (FDA) cautions that cholesterol-lowering drugs (statins) could increase the risk of reversible memory loss and confusion.

3. Hypothyroidism

The thyroid gland is a butterfly-shaped gland present in the front of the neck. It helps to regulate many body functions by constantly releasing a steady amount of thyroid hormones into the bloodstream. Hypothyroidism is the condition when thyroid gland stops releasing the required amount of thyroid hormone in the body. 

People with undiagnosed or untreated hypothyroidism may face memory problems and difficulty concentrating. 

Researches have also shown that people with untreated hypothyroidism present with a decrease in the size of the hippocampus, the part of the brain responsible for memory and learning.

Along with forgetfulness, other symptoms of hypothyroidism could be sudden weight gain, over-sensitivity to cold, dry skin even during summers and persistent hair loss.

4. Vitamin B12 deficiency

Vitamin B12 is one of the important elements that the body requires for the production of DNA, red blood cells and the proper functioning of the brain.

Vitamin B12 is also important for nerves as it helps in maintaining intact myelin sheaths (the protective covering around nerves). Deficiency of Vitamin B12 in a young person can possibly lead to reversible memory loss and dementia-like symptoms in them. 

Since vitamin B12 is not produced in the body, one needs to take it in forms of food and supplements.

5. Depression

Depression may lead to forgetfulness and state of confusion in the patient. Pseudodementia is a clinical state where the person is suffering from depression but mimics the symptoms of dementia. 

A person suffering from pseudodementia may present with symptoms like a delayed response to any stimuli, forgetting things and people, slurred speech, persistent sadness, feeling of fatigue, disturbed sleep, decreased appetite, low self-esteem, and suicidal ideation.

Why do I have memory loss in my 20s?

Research tracing the gradual decline of memory says that the process begins at the ripe age of 20 and as brain cells slip away, gone forever, the chemicals that help the brain work efficiently are also not being produced in the same quantities as when you were a fast-thinking teen.
