When it comes to memory loss, we have all heard of Alzheimer’s disease, Parkinson’s disease, Lewy body dementia, HIV, and a few other conditions. But, what are the different causes of memory loss? Are any of them treatable? Here’s a brief review of these diseases. These conditions are all treatable if detected early, so it is crucial to seek early medical evaluation. However, many people are afraid to see their doctor for fear of developing dementia.
Alzheimer’s disease
If you think your elderly loved one may be suffering from Alzheimer’s disease, there are a few warning signs. Some people with the disease may not even be able to remember basic facts. Others may be able to perform everyday activities but have difficulty focusing or remembering things. Some may even wander away from home. These symptoms are difficult to detect at an early stage and might be confused with changes that come with age.
Scientists believe that Alzheimer’s disease begins in the memory region of the brain and develops years before symptoms appear. The disease causes neurons to die and shrinks the brain by the late stages. Researchers have found that beta-amyloid protein clusters in the brain appear to be toxic to neurons, disrupting cell-to-cell communication. Other types of cellular debris are also present in the amyloid plaques.
Parkinson’s disease
The symptoms of Parkinson’s disease can impact a person’s memory, and can cause difficulty communicating with others. Speech becomes slurred, humour is hard to understand, and following conversations becomes difficult. This is because the brain’s signals are interrupted, and damaged memory areas make it difficult to recall information. These symptoms can make daily life tasks difficult for a person with Parkinson’s disease. These symptoms can also be aggravated by other factors, such as depression, stress, or certain medications.
A recent BWH Bulletin article highlighted a link between memory loss and the onset of the disease. A group of neuroscientists, including Dr. Carolyn Bernstein, have conducted fun science experiments with fourth graders to illustrate the link between memory loss and Parkinson’s disease. The students learned new scientific terms and how to distinguish between blinded and non-blinded experiments. This research could lead to new treatments and better ways to manage the symptoms of this disease.
Lewy body dementia
People with Lewy body dementia often have other symptoms as well. Movement problems are typically the first symptom to develop, but some people may experience these problems much earlier. Other symptoms may include tremors, rigidity, abnormally slow movement, impaired balance, postural instability, and diminished sense of smell. In rare cases, the person may also have an increase in saliva production. Unlike Alzheimer’s disease, however, dementia with Lewy bodies does not necessarily progress rapidly.
There is no specific test to diagnose Lewy body dementia, but doctors can make a preliminary diagnosis by reviewing the patient’s medical history, physical exam, and memory tests. In some cases, a physician may order blood tests to rule out other disorders or perform a detailed neuropsychological examination. In general, people with LBD are treated by movement disorder specialists or cognitive/memory specialists. Symptoms may appear suddenly, or slowly over time.
Dementia with Lewy bodies is not as common as Alzheimer’s disease, but it does affect 1.4 million people in the United States. Dementia with Lewy bodies is a condition caused by the buildup of abnormal proteins in the brain. These proteins affect mental capabilities, mood, and movement. It is similar to Alzheimer’s disease and Parkinson’s disease, but does not occur in younger adults.
HIV
A study in HIV and memory loss diseases aims to investigate the link between the virus and deteriorated thinking abilities. In this study, people with HIV will be matched with healthy volunteers and evaluated for a range of cognitive problems. Participants will undergo a medical history, physical examination, blood, urine, and neurological tests. They will also undergo a baseline brain imaging study. If the participant shows signs of memory problems, they will be invited to return for a second visit within 12 weeks. The second visit will involve another neurological test, additional blood samples, and a second brain imaging study.
MRI scans of the brain are typically conducted to detect the presence of HIV-1 DNA or proteins in brain tissue. Neurons with HIV infection may also undergo a lumbar puncture, which involves a needle inserted into the lower back to obtain a sample of cerebrospinal fluid. Cerebrospinal fluid is the fluid surrounding the brain and spinal cord and is used to monitor the spread of infections. HIV treatment can be effective in reducing this complication.
Tuberculosis
The relationship between TB and memory loss is well established, but the connection between the two conditions is complex and multifaceted. For example, patients with active TB may be asymptomatic and exhibit no symptoms. Likewise, patients with latent TB may display negative TST results and yet be susceptible to LTBI. Nevertheless, it is imperative to note that both TB and memory loss are connected and that treatment is critical.
In both conditions, the disease affects the brain and spinal cord. It is a complication of TB. If the disease is left untreated, tuberculosis can spread to the brain and cause TBM, an inflammation of the meninges that surrounds the brain and spinal cord. Symptoms of TBM may include headache, neurological problems, and coma. TBM is often fatal. This article will outline how to recognize the symptoms of both conditions, as well as the outlook for those suffering from these diseases.
The anti-TNF drug linezolid has been used to treat patients with drug-resistant TB, but it is expensive and a toxicity concern. Several new regimens involving novel compounds are being evaluated for TB treatment. If any new regimen or drug develops positive results, it may be a promising candidate for prevention. But, more research needs to be done to understand the link between TB and memory loss.
Herpes
Herpes and memory loss are two diseases that are closely related. The herpes simplex virus affects people in their youth and remains dormant in the peripheral nervous system. These herpes can reactivate during times of stress and cause cold sores. As our immune systems weaken, the virus can migrate to our brain and cause damage to brain cells. People with the APOE4 gene are particularly susceptible to this disease.
Although many patients will recover within a month from an acute herpes infection, more serious complications may develop without treatment. Herpes simplex encephalitis may cause brain damage and lead to problems thinking and controlling one’s body. In more severe cases, a person may require long-term care. Treatment options may include abstinence from sexual activity, testing all partners, or the use of latex condoms to reduce the risk of infection.
Researchers found a significant link between herpes and Alzheimer’s disease. Patients with HSV1 in the brain were 12 times more likely to develop Alzheimer’s than those without the virus, which is associated with amyotrophic lateral sclerosis. In fact, Dr. Gandy, associate director of the Mount Sinai Alzheimer’s Disease Research Center, believes that the effects of herpes are similar in both disease types. He believes that antiviral drugs can reduce the risk of Alzheimer’s disease by reducing the prevalence of herpes.
Nutritional deficiency
We all know that the brain loses some of its important nutrients as we age. However, what we often don’t realize is that a nutritional deficiency can impact our ability to recall and retain memories. While we may have a healthy diet that is rich in protein, fiber, vitamins, and minerals, our bodies can still suffer from nutritional deficiency. There are a few ways to improve your memory and prevent diseases like dementia.
One of the most common nutritional deficiencies is thiamine, which may be present in our diets. This nutrient is necessary for normal brain function and is often deficient in people. It may cause problems with skin, digestion, and growth. In addition, it may also cause problems with mental health, including dementia. People with this nutritional deficiency may experience any or all of these symptoms, and the problem may be as simple as not eating enough fruit and vegetables.
Epilepsy
In the early stages of epilepsy, treatment may consist of various measures, including neuropsychological testing and MRI. The latter will determine the side of the brain that is dominant in language, and will reveal whether there is an epileptic region that impairs memory function. In addition, functional MRI can predict the impact of epilepsy surgery on cognitive function. The procedure involves recording blood flow to different parts of the brain during cognitive tasks.
Antiseizure drugs, which are taken before a seizure, are a first line treatment for epilepsy. These drugs reduce the frequency and severity of seizures. However, they do not prevent seizures, which means that the patient cannot stop the seizures once they begin. Epilepsy medications travel through the bloodstream to the brain where they act to reduce or eliminate brain electrical activity. Different antiseizure medications are prescribed for different kinds of seizures.
A person with epilepsy may also have problems with attention, as seizures interfere with the ability to process information. This could lead to missed details or poor memories. The brain’s structure can also negatively impact the ability to retain information, resulting in a reduced attention span. If you have epilepsy, your treatment will include a program to correct any vitamin deficiency. Once you’ve treated the underlying disease, your memory problems will likely improve.
