Mechanism Of Cerebral Damage

Depression Can Cause Memory Loss and Difficulty Concentrating

The mechanism by which cellular and cerebral injury and death occurs is not yet fully defined, but is probably multi-factorial. It may be grouped into three broad areas some of these are explored briefly below.

Fig. 1

  • Cellular effects: membrane, mitochondrial and DNA damage, stimulation of excitotoxic mechanisms, protein denaturation

  • Local effects: ischaemia, inflammatory changes, oedema, cytokine release, vascular damage

  • Systemic effects: changes in cerebral blood flow, endotoxaemia, bacterial translocation through a dysfunctional gastrointestinal tract.

Radiological And Pathological Findings

Various radiological findings have been described on magnetic resonance imaging after heatstroke, including haemorrhage, oedematous changes, ischaemia, encephalitis, and atrophic changes , suggesting a number of pathological processes. Lesions have been observed throughout the central nervous system , including the brain stem, cerebellum, hippocampus, external capsule, and cerebrum . Haemorrhage on MRI may represent a poorer prognosisof eight patients in one follow-up study, three patients had evidence of haemorrhage on MRI imaging, and all three died. The remaining five showed no haemorrhage, and all survived .

Radiological lesions are often bilateral , in keeping with the clinical findings. However, clinical features and radiological signs may correlate poorly. Clinical signs may improve and resolve, despite progressive or non-resolving radiological signs . Radiological signs may improve despite little clinical improvement , or signs may deteriorate with minimal clinical change and progression to atrophy may occur . Imaging may show defects in areas of the brain without clinical deficits or may be normal, despite profound clinical deficits . Deficits on imaging may develop late imaging may be normal on presentation, and abnormalities only evident on repeat imaging. MRI is probably more sensitive than computed tomography.

What Is Memory Loss After Stroke

You might experience the following types of memory loss:

  • Verbal: memory of names, stories and information having to do with language
  • Visual: memory of shapes, faces, routes and things seen
  • Informational: memory of information and skills or trouble learning new things
  • Vascular dementia: A common post-stroke condition involving loss of thinking abilities

Symptoms of memory loss after a stroke may include:

  • Confusion or problems with short-term memory
  • Wandering or getting lost in familiar places
  • Difficulty following instructions
  • Trouble making monetary transactions
  • Memory loss may be a direct result of stroke but can also be caused or worsened by medications use of alcohol, tobacco and drugs lack of sleep depression and stress or poor nutrition.

Heat Exhaustion Versus Heat Stroke

Heat exhaustion, if left untreated, can lead to heatstroke.

Unlike heatstroke, which can be life-threatening, heat exhaustion does not cause impaired mental function, confusion, or loss of consciousness.

Cases of heat exhaustion are also distinguished from heatstroke because a persons internal body temperature does not go above 103°F.

Heat stroke is less common than heat exhaustion but more serious it puts strain on the heart, lungs, kidneys, and liver.

Heat exhaustion is most often caused by a combination of physical exertion and warm weather.

Additional factors known to increase the likelihood of heat exhaustion include:

  • high humidity, usually over 60 percent
  • liver or kidney conditions

If heat exhaustion is suspected, a person should stop doing exercise or physical activity immediately. A person with heat exhaustion should also drink fluids as soon as possible.

Further tips for treating heat exhaustion include:

  • seeking out a cool, shaded area or going indoors
  • loosening clothing
  • lying flat on the back
  • taking a lukewarm or cool shower
  • placing a cool, wet cloth on the face and chest
  • in severe cases, putting ice packs under each armpit and behind the neck
  • drinking 1 liter per hour of drinks that contain electrolytes, such as Gatorade or Gastrolyte

How Long Do Side Effects Last

Remember that the type of radiation side effects you might have depends on the prescribed dose and schedule. Most side effects go away within a few months of ending treatment. Some side effects may continue after treatment ends because it takes time for the healthy cells to recover from radiation.

Side effects might limit your ability to do some things. What you can do will depend on how you feel. Some patients are able to go to work or enjoy leisure activities while they get radiation therapy. Others find they need more rest than usual and cant do as much. If you have side effects that are bothersome and affecting your daily activities or health, the doctor may stop your treatments for a while, change the schedule, or change the type of treatment youre getting. Tell your cancer care team about any side affects you notice so they can help you with them.

If Youre Getting Radiation Therapy To The Brain

People with brain tumors often get stereotactic radiosurgery if the cancer is in only one or a few sites in the brain. Side effects depend on where the radiation is aimed. Some side effects might show up quickly, but others might not show up until 1 to 2 years after treatment. Talk with your radiation oncologist about what to watch for and when to call your doctor.

If the cancer is in many areas, sometimes the whole brain is treated with radiation. The side effects of whole brain radiation therapy may not be noticeable until a few weeks after treatment begins.

Radiation to the brain can cause these short-term side effects:

  • Headaches
  • Trouble with memory and speech
  • Seizures

Some of these side effects can happen because radiation has caused the brain to swell. Medicines are usually given to prevent brain swelling, but its important to let your cancer care team know about headaches or any other symptoms. Treatment can affect each person differently, and you may not have these particular side effects.

Radiation to the brain can also have side effects that show up later usually from 6 months to many years after treatment ends. These delayed effects can include serious problems such as memory loss, stroke-like symptoms, and poor brain function. You may also have an increased risk of having another tumor in the area, although this is not common.

Talk with your cancer care team about what to expect from your specific treatment plan.

Memory Loss Cause # 4 Vitamin Deficiency

Memory Loss and Concentrating Issues

Nutritional deficiencies have been known to be the root of numerous disorders, from scurvy, a vitamin C shortage, to weakening of bones, which is mostly pertaining to a lack of calcium and also vitamin D in the diet regimen. It is estimated that fifty percent of all elders are vitamin D lacking, as well as even less senior citizens get sufficient vitamin C. Vitamin shortage can create moderate to extreme cognitive decrease, so its crucial to be knowledgeable about your nutritional needs.

The vitamins that research studies have actually revealed to affect memory loss and also cognition are:.

Vitamin A.B12, known to aid cognition in healthy and balanced brains however is particularly handy for dementia.Folic acid.Vitamin C.Vitamin D.

Your physician will have the ability to assist you in what vitamins to take, remembering your current prescriptions. Its important to keep in mind that water is also a crucial active ingredient to a properly maintained body, and dehydration is carefully linked to cognitive decrease. A current survey records that 56% of seniors drink less than 6 glasses of water a day, 2 less than the suggested daily amount.

Common Causes Of Forgetfulness

Memory slips are aggravating, frustrating, and sometimes worrisome. When they happen more than they should, they can trigger fears of looming dementia or Alzheimers disease. But there are some treatable causes of forgetfulness. Here are six common ones.

Lack of sleep. Not getting enough sleep is perhaps the greatest unappreciated cause of forgetfulness. Too little restful sleep can also lead to mood changes and anxiety, which in turn contribute to problems with memory.

Medications. Tranquilizers, antidepressants, some blood pressure drugs, and other medications can affect memory, usually by causing sedation or confusion. That can make it difficult to pay close attention to new things. Talk to your doctor or pharmacist if you suspect that a new medication is taking the edge off your memory. As shown in the table below, alternatives are usually available.

Medications that may affect memory and possible substitutes

Can You Treat Dementia After Stroke

With vascular dementia, there is hope for improvement through cognitive rehabilitation, which is possible thanks to neuroplasticity.

Neuroplasticity is the process the brain uses to rewire itself and form new connections, as well as strengthen existing connections. When part of the brain sustains damage after a stroke, neuroplasticity allows healthy areas of the brain to take over. However, it does not occur without your help.

In order for neuroplasticity to work, the brain needs to see a demand for a function. For example, the brain wont improve at the skill of riding a bike unless you attempt to ride a bike in the first place, because this shows a demand for that function. To apply this concept to cognitive health, this is where cognitive rehabilitation exercises come into play.

Cognitive exercises draw upon desired thinking skills, such as memory and attention. When the brain sees a demand for these skills, it will attempt to adapt. For example, by practicing memory exercises, the brain perceives the demand for the function of memory, and it responds by creating and strengthening neural pathways responsible for memory.

Stay Cool And Hydrated

While its worrisome how heat can significantly affect our performance, experts say its only temporary and various cooling methods can mitigate the negative impacts.

For instance, drinking regularly and eating foods with high water content is an easy and cost-effective way to combat the heat during hot days. Hydration has its own positive impacts on cognitive function, and drinking water helps support sweating which leads to evaporative cooling, Varshney says. In addition to the aforementioned studies, other journal articles also document how buildings with air conditioning systems adequately improve thermal conditions, increasing the performance and cognitive function of students and office workers.

Drinking water, using fans, and installing air conditioning are all excellent solutions for optimal functioning of the body and the brain, Mahajan says. Other simple ways to keep the room cool, like keeping the curtains drawn to avoid direct sunlight, may be effective as well. However, these solutions only temporarily address one facet of a growing problem: climate change. Hotter days become more common and heat waves more intense due to global warming, which can lead to more heat-related illnesses.

Risk Factors For Heat Stroke

A kinase

Heat stroke is most likely to affect older people who live in apartments or homes lacking air conditioning or good airflow. Other high-risk groups include people of any age who don’t drink enough water, have chronic diseases, or who drink excessive amounts of alcohol.

Heat stroke is strongly related to the heat index, which is a measurement of how hot you feel when the effects of relative humidity and air temperature are combined. A relative humidity of 60% or more hampers sweat evaporation, which hinders your body’s ability to cool itself.

The risk of heat-related illness dramatically increases when the heat index climbs to 90 degrees or more. So it’s important — especially during heat waves — to pay attention to the reported heat index, and also to remember that exposure to full sunshine can increase the reported heat index by 15 degrees.

If you live in an urban area, you may be especially prone to develop heat stroke during a prolonged heat wave, particularly if there are stagnant atmospheric conditions and poor air quality. In what is known as the “heat island effect,” asphalt and concrete store heat during the day and only gradually release it at night, resulting in higher nighttime temperatures.

Other risk factors associated with heat-related illness include:

Age. Infants and children up to age 4, and adults over age 65, are particularly vulnerable because they adjust to heat more slowly than other people.

What Do You Do For Heat Stroke

Heat exhaustion and heatstroke treatment

  • Get out of the heat quickly and into a cool place, or at least shade.
  • Lie down and elevate your legs to get blood flowing to your heart.
  • Take off any tight or extra clothing.
  • Apply cool towels to your skin or take a cool bath.
  • Drink fluids, such as water or a sports drink.
  • Getting Your Memories Back

    In cases where hearing loss has affected your memory, either via mental exhaustion or social isolation, treatment of your underlying hearing problem is the first step in treatment. When your brain stops overworking and overstressing, itll be able to return to its normal activities. It can take a few months for your brain to re-adjust to hearing again, so be patient.

    The red flags raised by your memory loss could help you be a little more conscious about protecting your hearing, or at least treating your hearing loss. As the years start to add up, thats definitely a lesson worth remembering.

    What Is The Connection Between Stroke And Memory Loss

    Stroke and memory loss are closely connected, as strokes can damage the brain and brain damage causes memory loss. Stroke survivors commonly report at least some memory loss in association with their strokes. The good news is that this is often reversible through rehabilitation and therapy, although not always. After a patient has had a stroke, a rehabilitation specialist should visit the patient in the hospital to perform an assessment and make an accurate estimate of the patient’s ability to recover.

    When people experience strokes, part of the brain is injured due to hemorrhage, increased pressure, or lack of blood supply. The brain is a very flexible organ and can often adapt, with time, to injuries, depending on the location of the damage. When strokes involve the areas of the brain where memories are formed and stored, patients can develop memory loss. Some may experience a rewiring of their brains after the event, allowing them to recover their cognitive abilities, while others may have permanent memory problems.

    Memory can improve over time, either spontaneously or through rehabilitation, but symptoms can last for years. Your memory loss may benefit from medications for related problems, such as anxiety, depression or sleeping problems.

    Brain retraining techniques are designed to improve your thinking and memory after a stroke. The training can help improve alertness and attention, but theres no scientific proof that such therapy can improve your ability to carry out daily tasks. This training can be done in person as well as with computer programs and applications. To stimulate your brain and improve memory and cognitive ability, you can try new hobbies that involve both the mind and body. Also, exercise: Physical fitness adds to overall physical and mental health.
