Your memory might feel bad at 18 due to common factors like stress, lack of sleep, and poor diet, which impair focus and memory consolidation, especially with added pressures from school or life changes, but also consider potential underlying issues like anxiety, depression, ADHD, or even past trauma, all of which affect attention and recall; seeking professional advice is key if it significantly impacts your life.
Not getting enough sleep, stressing over too many activities or vitamin deficiencies are all common reasons why teens struggle with short-term memory. Eating too much junk food early in life was linked to poor memory in one study. Use of substances like alcohol and marijuana also impacts memory.
Substance use: alcohol, recreational drugs, and heavy nicotine use harm memory formation and retrieval. Medical and neurological causes: vitamin B12 deficiency, thyroid dysfunction, untreated sleep apnea, chronic infections, head injury, and early neurodegenerative disease can cause progressive memory decline.
Stay mentally active
Just as physical activity keeps your body in shape, activities that engage your mind help keep your brain in shape. And those activities might help prevent some memory loss. Do crossword puzzles. Read.
At present, there's no way to treat memory loss itself. The main approach is to recognize and eliminate the underlying cause if possible, making it as easy as possible for your brain to heal.
Depression can mimic dementia, and appropriate treatment can reverse depression-related memory deficits. “Correcting these issues may help improve memory loss,” Dr. Parulekar says. On the other hand, memory loss resulting from brain disorders like Alzheimer's disease and dementia cannot be reversed.
These include:
Differentiating ADHD from Other Memory Problems
ADHD can also mimic dementia, another condition that affects memory. However, the two can be differentiated by examining present symptoms and when they appeared. Dementia alters a person's ability to recall information they used to be able to.
New research indicates that being forgetful doesn't mean you're losing your marbles, in fact, it could mean that you are exceptionally intelligent. People with the best memories in the long term usually forget details once they are no longer needed.
Here are 6 strategies that may help minimize brain fog symptoms.
Five significant signs your brain might be in trouble include memory loss (especially recent events), difficulty with familiar tasks or language, confusion about time/place, significant personality/behavior changes, and problems with judgment, focus, or coordinating movement, often indicating conditions like dementia, brain injury, or other neurological issues, requiring a doctor's visit.
Individuals who have ADHD tend to have underperforming working memory. This underperformance causes people to forget what they just did, where they placed something, or even what they meant to say while speaking.
The 2-7-30 Rule for memory is a spaced repetition technique that boosts retention by reviewing new information at specific intervals: 2 days, 7 days, and 30 days after the initial learning, leveraging the brain's forgetting curve to solidify knowledge into long-term memory with minimal effort, making it great for studying languages, skills, or complex topics.
Young onset dementia affects people aged 18 to 64
Dementia is a word medical doctors use when an illness or other situation is making it very hard for someone to remember, move, think or connect. For medical doctors to use this word—dementia—those problems must be intense enough to affect someone's daily life.
At this time, forgetfulness in teenagers may be because of planning, memory, and the ability to control social behaviors that have been affected by the development taking place in the brain. Forgetfulness becomes inevitable with the constant evolution that the brain undergoes during adolescence.
Other early symptoms might include:
No, an IQ of 97 is not considered dumb; it falls within the average range (90-109), indicating typical cognitive abilities, and is very close to the theoretical average of 100, meaning you're more intelligent than about 42% of people and have normal intelligence, just slightly below the mean, but well within the typical range for most adults.
An IQ of 72 is considered borderline intellectual functioning, falling below the average range (90-109) but not quite low enough for a diagnosis of intellectual disability (typically below 70). It signifies slower learning, potential difficulties with complex concepts, and a need for more support in daily living and academic skills, placing someone in the bottom few percentiles of the population.
Having a bad memory is a sign of high intelligence. If you have a hard time remembering, it's a good indication that your brain is more focused on the essential things. Packing your brain full of memories for an exam or a business meeting is overrated and could harm your chances of success.
The ADHD "30% Rule" is a guideline suggesting that executive functions (like self-regulation, planning, and emotional control) in people with ADHD develop about 30% slower than in neurotypical individuals, meaning a 10-year-old might function more like a 7-year-old in these areas, requiring adjusted expectations for maturity, task management, and behavior. It's a tool for caregivers and adults with ADHD to set realistic goals, not a strict scientific law, helping to reduce frustration by matching demands to the person's actual developmental level (executive age) rather than just their chronological age.
Here are some tips:
Someone with ADHD is more likely to seek out novelty and make more impulsive decisions, whereas an autistic person is more likely to crave routine and structure.
No matter what your age, several underlying causes can bring about memory problems. Forgetfulness can arise from stress, depression, lack of sleep or thyroid problems. Other causes include side effects from certain medicines, an unhealthy diet or not having enough fluids in your body (dehydration).
Although the early signs vary, common early symptoms of dementia include:
When you learn something new, the best way to remember it is to sleep on it. That's because sleeping helps strengthen memories you've formed throughout the day. It also helps to link new memories to earlier ones. You might even come up with creative new ideas while you slumber.
