What Are Memory Disorders?
But when memory impairment starts to interfere with your daily tasks, social activities, and work, you might have a memory disorder.
Memory disorders are problems associated with communication, decision making, recollection, reasoning, and cognitive skills. A memory problem could also occur due to neurological damage to your brain structure.
Besides causing immense psychological stress, they also affect your ability to create, store, and recall memories.
Memory impairment could occur due to:
- A side effect of medication
- Brain impairment
- Trauma to the head
- Substance abuse
- Vitamin deficiencies
- An untreated metabolic disease or infection
- Cardiovascular disease
It’s tough to pinpoint the actual reason for memory disorders. And this is what makes their diagnosis challenging.
Curious to know if your memory problem is a memory disorder?
Let’s find out.
Do Age-Related Memory Problems Always Mean Memory Disorders?
Cognitive decline usually develops with age. Older adults with no memory disorder problems may pause to remember directions, but they do not get lost in familiar places.
Forgetting where you kept your reading glasses is just a sign of normal aging. In this normal aging process, your judgment remains intact, and the memory problem doesn’t affect your routines.
However, if an older adult starts forgetting what reading glasses are and how they are used, it could point to a memory disorder.
Research indicates that the amount of hippocampal neurofibrillary tangles or protein deposits in the cortex help differentiate between normal aging and a memory disorder.
Are all memory disorders alike?
Short answer: No.
Different memory disorders have different progress rates and involve different brain structures.
Some memory disorders like Alzheimer’s are progressive, and it may take years before the symptoms appear. Others like frontotemporal dementia are also progressive and cause reduced brain function in the frontal and temporal lobes.
Damage to brain function caused by traumatic brain injury like a car crash has an immediate effect.
Some of these cognitive disorders can be treated, while others like anterograde amnesia don’t have a cure yet. However, there are many scientific solutions to assist patients to go about their daily lives.
Early clinical assessment can help determine the future course of action. Behavioral neurologists can assess the patient to understand the extent of cognitive impairment.
Patients can take remedial steps by attending a memory disorders program to manage symptoms and improve their quality of life.
5 Memory Disorders: Symptoms, Diagnosis, and Treatment
1. Alzheimer’s Disease
Alzheimer’s Disease is a neurodegenerative disease – a type of dementia – which causes problems with memory, thinking, and behavior. It also happens to be the sixth leading cause of death in the world!
Alzheimer’s Disease is named after Dr. Alois Alzheimer, who reported “a peculiar severe disease progress of the cerebral cortex” in 1906 in Tubingen to the 37th Meeting of South-West German Psychiatrists.
Symptoms of Alzheimer’s Disease
Alzheimer’s disease is most common in people above the age of 65. This is called late-onset Alzheimer’s disease. The other two types are early-onset Alzheimer’s disease, which typically occurs in people of the 40-50 age group, and Familial Alzheimer’s disease which is linked to genes.
Alzheimer’s symptoms develop gradually, worsen over time, and eventually affect all everyday tasks.
The typical symptoms of people with Alzheimer’s disease are:
- Memory loss that worsens gradually
- Changes in mood and behavior
- Trouble communicating with others
- Confusion about time, place and events
- Difficulty walking, swallowing food, and speaking
How Does Alzheimer’s Disease Affect the Brain?
Alzheimer’s disease AD damages nerves, degenerates brain tissue, and leads to the accumulation of an abnormal protein called beta-amyloid and the development of neurofibrillary tangles.
It affects the hippocampus first, which is why memory loss is often the first symptom in a person with Alzheimer’s disease. Microglia cells then create inflammation to start the immune response, which further damages the brain. Eventually, it affects the entire brain.
Diagnosis of Alzheimer’s Disease and Treatment
There is no single Alzheimer’s disease and memory test or any particular cognitive test to detect Alzheimer’s disease.
Because of this, an Alzheimer’s disease center will use a combination of factors and tests such as:
- Detailed medical history
- Assessment of Alzheimer’s disease memory, problem-solving, and other mental abilities
- Standard blood and urine tests
- Brain imaging, such as CT, MRI, or PET scans
There is no cure for Alzheimer’s disease, yet.
Take any Alzheimer’s disease research center, and you’ll find several ongoing clinical trials that attempt to slow down the progress of the disease.
People in the early stages can enhance their cognitive function and manage the signs of Alzheimer’s disease with medication. They can also use behavioral treatments like speech therapy, and technological solutions like smart wearable devices along with medication.
Patients can also seek help from health organizations like the Alzheimer’s Association or any Alzheimer’s disease center for care and support.
Dementia is a neurological disorder that makes it harder for individuals to remember, communicate, and reason with others. It is caused by constant damage to the brain cells.
There are different types of dementia, including Alzheimer’s and Lewy body dementias. (The Lewy body disease is associated with abnormal deposits of the alpha-synuclein protein in the brain.)
Symptoms of Dementia:
There are a few common symptoms:
- Memory loss that interferes with familiar tasks
- Trouble with language — understanding and expression (like in Parkinson’s disease)
- Problems with judgment
- Personality changes
How Does Dementia Change the Brain?
Most changes that occur in the brain due to dementia are permanent and get worse over time. It interferes with the ability of brain nerve cells to communicate with each other. Different types of dementia affect different brain regions first.
Diagnosis of Dementia
Dementia can be diagnosed using:
- Neuropsychological tests where a neuropsychologist assesses mental functioning
- Analysis of bodily fluids such as blood, urine, and saliva
- Brain scans to identify changes in the brain structure
- Psychiatric evaluation
Treatment for Dementia
A disease like dementia is incurable. Medicines and therapy can only make dementia patients feel better temporarily.
The good news is, people with dementia can live comfortably by routinely exercising and engaging in some form of activity.
Assistive technology can help dementia patients stay independent and safe as long as possible. For example, Google calendar to help them remember things to do, and video calling apps to help them connect with their loved ones.
Routine health checkups are also a vital part of a dementia patient’s life.
3. Mild Cognitive Impairment
Mild cognitive impairment (MCI) is a transitional state between dementia and normal memory and thinking (cognitive abilities). It is a slight yet noticeable cognitive decline.
Individuals with mild cognitive impairment have more difficulty with memory, language, and thinking than others their age. They also have a high risk factor of developing dementia or Alzheimer’s.
However, some mild cognitive impairment patients remain at a stable state or regain their normal cognitive abilities over time.
Symptoms of Mild Cognitive Impairment
There are two types of mild cognitive impairment — Amnestic MCI and NonAmnestic MCI. Amnestic MCI deals primarily with memory loss, and NonAmnestic MIC deals mostly with a decline in thinking skills.
Here are some symptoms of Mild Cognitive Impairment:
- Impulsive behavior
- Getting overwhelmed while doing simple tasks
- Forgetting appointments and other social engagements
- Feeling lost and confused
How Does Mild Cognitive Impairment Impact the Brain?
The changes in the brain are similar to Alzheimer’s dementia but less intense.
Mild Cognitive Impairment results in:
- Shrinkage of the hippocampus
- Enlargement of ventricles
- Reduced use of glucose
- Abnormal clumps and tangles of nerve cells
- Reduced blood flow through brain blood vessels
Diagnosis of Mild Cognitive Impairment
For the diagnosis of mild cognitive impairment, the doctor looks into:
- A complete medical history
- Inputs from a family member or a close friend about daily activities
- Psychiatric evaluation to trace signs of depression
- Brain imaging
- Behavioral neurology examination
These evaluations have to be done every six months as patients with mild cognitive impairment are at increased risk of dementia and Alzheimer’s disease.
Treatment for Mild Cognitive Impairment
The treatment mostly focuses on managing or easing symptoms. Medications are used only in cases of significant memory changes or for someone who is also exhibiting symptoms of Parkinson’s.
Those experiencing depression often benefit from psychotherapy. Treating other underlying conditions such as cholesterol and hypothyroidism is also a good idea.
Lifestyle changes and maintaining cognitive health can allow patients with Mild Cognitive Impairment to stabilize their condition without making it worse.
4. Autoimmune Encephalitis
Autoimmune Encephalitis is a rare disease that occurs when the body’s immune system attacks healthy brain cells and causes inflammation.
This disease is caused by viruses, including rabies, herpes simplex virus, toxoplasmosis, and the West Nile virus.
Symptoms of Autoimmune Encephalitis
Initially, some patients may exhibit neurological or psychiatric symptoms, and that makes this disease tricky to diagnose.
The symptoms could be:
- Tremors (like in people with Parkinson’s disease dementia)
- Involuntary movements
- Loss of inhibition
- Severe insomnia
- Loss of balance
How Does Autoimmune Encephalitis Affect the Brain?
The body’s immune system attacks healthy brain cells, leading to inflammation in the brain.
Diagnosis of Autoimmune Encephalitis
This disease is challenging to diagnose, as the symptoms appear at different times with different intensity levels.
Patients need to meet these criteria:
- Rapid progression of working memory deficits, altered memory status, or psychiatric symptoms.
- And one of these criteria should be met:
- New focal CNS findings
- Unexplained seizures
- Increased white blood cell count
- MRI suggests encephalitis
Treatment of Autoimmune Encephalitis
Early detection and quick treatment are necessary for the treatment of this disorder. Patients should be hospitalized immediately. The treatment is focused on preventing complications, reducing swelling, and controlling seizures and fevers.
5. Vascular Cognitive Impairment
Vascular Cognitive Impairment is a common form of dementia in older adults. It is caused by decreased blood flow to the brain, which eventually damages the brain tissue.
There are many types of vascular dementia, including:
- Mixed dementia, where symptoms of both vascular dementia and Alzheimer’s disease exist.
- Multi-infarct dementia where the blood flow affects a specific part of the brain.
- Stroke-related and post-stroke dementia may also be a cause of vascular cognitive impairment.
Symptoms of Vascular Cognitive Impairment
Symptoms of Vascular Cognitive Impairment could develop gradually or appear suddenly after a stroke.
- Inability to carry out instructions
- Concentration and communication problems
- Memory loss
- Movement troubles (like people with Parkinson’s disease)
- Urinary problems
How Does Vascular Cognitive Impairment Affect the Brain?
The effect of vascular cognitive impairment depends on the location and size of the affected area in the brain. It occurs due to blood clots, ruptured blood vessels due to atherosclerosis, high blood pressure, and infection.
Diagnosis of Vascular Cognitive Impairment
Doctors conduct the following tests in addition to taking a detailed medical history and physical examination:
- Brain scans such as CT, PET, and MRI
- Electroencephalogram (EEG) of the brain
- Neuropsychological and neuropsychiatric tests
Treatment of Vascular Cognitive Impairment
Vascular Cognitive Impairment cannot be cured. Any treatment will only manage the associated conditions.
Doctors could advise:
- Medicines to control blood pressure, diabetes, and blood clotting
- Procedures like angioplasty to improve blood flow to the brain
- Lifestyle changes, including exercises for cognitive stimulation and cognitive rehabilitation.
With so many complications associated with memory disorders, it is imperative to diagnose them early.
Here are a few more reasons why it’s essential to do so.
Why Must Memory Disorders Be Diagnosed Early?
Early diagnosis can:
- Explain your symptoms and reduce your anxiety
- Give you access to treatments to slow down the disease
- You could find a place in a clinical trial for a miracle drug
- Give you time to prepare for the future, both emotionally and financially
- Help you to preserve your cognitive skills and abilities
There is a cultural aspect to it as well.
In many societies, there is a stigma against those who suffer from mental illness. There have been several cases of patients being denied jobs, denied places to stay, and having false criminal charges levied against them.
Keeping all these factors in mind, prevention is definitely better than a cure.
You may be able to delay or prevent the onset of memory loss by merely exercising your brain regularly!
A regular brain workout will be extremely helpful even if you’re only struggling with minor memory loss.
How do you do that?
Build Memory Palaces And Give Your Brain a Workout
Creating a Memory Palace stimulates your spatial memory, visual memory, recovered memory, and autobiographical memory.
So, if you forget what day of the week it is, try this out:
- When you wake up in the morning, imagine you’re looking at a gift box with seven boxes within.
- In each box, place an image. For example, in the first box (Monday) place a man. In the Tuesday box, place a truck. On Wednesday, a walrus, and so on.
- These mnemonics will help you remember the day when you wake up.
- Remember to mentally cross out the day’s symbol and keep the day’s box aside before you hit the bed.
- This way, you will think of what happened yesterday when you wake up and instantly remember the day.
You can remember pretty much anything using a Memory Palace — names, faces, grocery items, a new language, academic material… the list is nearly endless.
Attaching physical locations to memories helps you access them with ease.
Building Memory Palaces is a technique you can use for life. Once you build one and master using it, you can create plenty more with ease.
And, if you can do that – like Sherlock Holmes – you can do great things with your memory.
