Signs Of Dying In The Elderly With Dementia

What other diseases LOOK LIKE dementia? | Dr. Marc

Dementia is a general term for a chronic or persistent decline in mental processes including memory loss, impaired reasoning, and personality changes. Alzheimers disease is the most common form of dementia, accounting for 60-80% of all cases of dementia. It is also the 6th leading cause of death in the United States, and over 5 million Americans are currently living with Alzheimers disease.

Alzheimers disease and most progressive dementias do not have a cure. While the disease inevitably worsens over time, that timeline can vary greatly from one patient to the next.

Caring for a loved one can be challenging and stressful, as the individuals personality changes and cognitive function declines. They may even stop recognizing their nearest and dearest friends and relatives. As dementia progresses, the individual will require more and more care. As a family caregiver, its important to be able to recognize the signs of dying in elderly with dementia. Hospice can help by offering care wherever the individual resides, providing physical, emotional and spiritual care to the patient and support their family.

Where Is Your Brain Located

Your brain fills the upper part of your bony head, which is called the skull. The top part of the skull, called the cranium, is made of 8 bones. The rest of your skull includes 14 bones in the face and 3 small bones in each ear. How about that! Altogether, there are 28 bones in your skull, and your brain is tucked safely inside, protecting it from most minor bumps and blows. Learn more about the skull at this Neuroscience For Kids site.

Is Dementia Hereditary

Genes can play a role in the development of dementia, but patterns of inheritance dramatically vary. In some cases, Alzheimer’s disease starts early and occurs often in some families. This is known as early-onset familial Alzheimer’s disease. Researchers have found that many of the family members affected have mutation in genes on chromosome 1 and 14. The pattern in which Alzheimer’s affects families is still uncertain. However, several risk factors for developing some types of dementia have been identified. These factors include:

What You Need To Know

  • Lewy body dementia is a form of progressive dementia that affects a persons ability to think, reason, and process information.
  • Diagnosing Lewy body dementia can be challenging an estimated 1.4 million Americans are living with the disease.
  • LBD has three features that distinguish it from other forms of dementia:
  • Fluctuating effects on mental functioning, particularly alertness and attention, which may resemble delirium
  • Recurrent visual hallucinations
  • Parkinson-like movement symptoms, such as rigidity and lack of spontaneous movement.
  • Interventions used in other forms of dementia may help people living with Lewy body dementia. Its important to work with a specialist familiar with the many aspects of the disease.
  • Lewy bodies are clumps of abnormal protein particles that, for reasons that are not fully understood, accumulate in the brain. These deposits cause a form of dementia called Lewy body dementia, or LBD which is what the late actor and comedian Robin Williams suffered from.

    LBD is not the same as Parkinsons, but the two are closely related: LBD causes some or all of the motor symptoms of Parkinsons. More than 1 million people in the U.S. are affected by Lewy body dementia, according to the Lewy Body Dementia Association.

    Many other conditions can cause dementia, including:

    • Low oxygen in the blood , either from a specific incident , or chronic disease can cause damage to brain tissue.
    • Acute infections such as meningitis, encephalitis, untreated syphilis, and Lyme disease.
    • Brain tumors or metastases from other cancers in the body.
    • Thiamine , B6, or B12 deficiencies, and severe dehydration.
    • Acute traumatic injury to the brain such as a subdural hematoma.
    • Side effects from medications taken for other medical conditions.
    • Electrolyte abnormalities.
    • Poisoning such as exposure to lead, other heavy metals, alcohol, recreational drugs, or other poisonous substances.

    What Does Lewy Body Dementia Look Like

    Lewy body dementia affects a persons ability to think and process information and it can negatively impact memory and alter personality. Though it shares aspects of other forms of dementia, there are distinct hallmarks of LBD. Lewy body dementia symptoms include:

    • Fluctuating attention/alertness: These shifts can last hours or go on for days. The person may stare into space, appear lethargic or drowsy, and have hard-to-understand speech, appearing a lot like delirium. At other times, the person may have much more clarity of thought.
    • Visual hallucinations: Often, these are very detailed hallucinations and visions of people or animals, and they can recur.
    • Movement disorders: Parkinsons-like movement issues, such as muscle rigidity, tremors, falls, or a shuffling gait or way of walking, may occur.

    Alzheimer’s Disease Symptoms And Treatment

    Patients with Alzheimer’s disease suffer progressive disability over the course of the illness. Generally, patients with Alzheimer’s can live from 2 to 20 years from diagnosis on average patients’ life expectancy is 8-10 years. Alzheimer’s disease usually causes a decline in thinking ability, memory, movement, and language. Bizarre, withdrawn, or paranoid behavior may also occur as the disease progresses.

    Early in the disease, patients may only have subtle symptoms such as changes in personality or lapses in memory. As the disease worsens, patients may experience bouts of disorientation, and may notice difficulty in performing daily tasks. In later stages of the disease, patients can no longer care for themselves, and they may become paranoid or hostile. In the later stages of the disease patients lose the ability to swallow and control bladder and bowel functions. They may no longer recognize family members and may not be able to speak. Fatal complications of Alzheimer’s include loss of ability to swallow that can lead to aspiration pneumonia, and incontinence leading to urinary tract infections or sepsis .

    Loss Of Neuronal Connections And Cell Death

    In Alzheimers disease, as neurons are injured and die throughout the brain, connections between networks of neurons may break down, and many brain regions begin to shrink. By the final stages of Alzheimers, this processcalled brain atrophyis widespread, causing significant loss of brain volume.

    Your Brain Is Mostly Fat

    Imaging Dementia-Mayo Clinic

    Consisting of minimum 60% fat, your brain is the fattiest organ in your body. This is why healthy fats, such as omega-3s and omega-6s, are vital for brain and overall body health. Healthy fat helps stabilize the cell walls in the brain. It can also reduce inflammation and helps the immune system function properly.

    A few MRI scoring systems contribute to grading the severity of dementia which will in turn guide management of the disease. Examples of scoring systems include the Global Cortical Atrophy scale, Medial Temporal lobe Atrophy scale, Koedam score for parietal lobe atrophy and Fazekas scale for white matter lesions/ vascular disease.

    Dementia however, is not diagnosed based on imaging alone. It is diagnosed based on a combination of tests, ranging from a clinical history, assessment on mental ability such as memory and communication, lab tests and scans. Scans are utilised in this aspect mainly to i) exclude a structural/ surgical cause and ii) grade brain changes in dementia.

    Symptoms of dementia vary, depending on stage of the disease. Early symptoms of dementia are memory loss, being confused about time and place, mood changes and difficulty carrying out simple, usual daily tasks. At this stage, the disease is termed mild cognitive impairment. As the disease progresses, these symptoms worsen and the term dementia is used. Symptoms of dementia proper and advanced dementia are regular forgetfulness, difficulty finding the right words, difficulty with numbers and handling money, mobility issues, becoming more withdrawn or anxious, bladder or bowel incontinence, amongst others.

    Brain Activity Can Power A Small Light Bulb

    When you are awake, your brain generates about 12-25 watts of electricity which is enough to power a small light bulb. The brain also works fast. The information going from your arms/legs to your brain travels at a speed of 150-260 miles per hour. The brain consumes glucose from the body to produce this amount of the energy.

Like most senior animals, aging cats can develop dementia, and from this point on, your cat is at increased risk. It is harder for him to learn new things and adjust to change now, and he may get confused more easily.

    Brain tumors are a possibility for older cats who show signs of dementia. Tumors can lead to seizures and collapse, but all kinds of abnormal behavior such as incoordination or reacting to invisible objects are suspect, too.

    Cholesterol Is Key To Learning And Memory

    The brain has a higher cholesterol content than any other organ. In fact, about 25% of the bodys cholesterol resides within the brain. The brain is highly dependent on cholesterol, but its cholesterol metabolism is unique. Because the blood-brain barrier prevents brain cells from taking up cholesterol from the blood, the brain must produce its own cholesterol. The brains cholesterol is much more stable than the cholesterol in other organs, but when it breaks down, it is recycled into new cholesterol right in the brain.

    The healthy human brain contains tens of billions of neuronsspecialized cells that process and transmit information via electrical and chemical signals. They send messages between different parts of the brain, and from the brain to the muscles and organs of the body. Alzheimers disease disrupts this communication among neurons, resulting in loss of function and cell death.

    How Hospice Can Help With End

    In addition to helping you in recognizing the signs of dying in the elderly with dementia, bringing in hospice care will help with the physical and emotional demands of caregiving. Nurses will be able to adjust medication and care plans as the individuals needs change. Aides can help with bathing, grooming, and other personal care. Social workers can help organize resources for the patient and family. Chaplains and bereavement specials can help the family with any emotional or spiritual needs. Additionally, family members can contact hospice at any time, and do not need to wait until it is recommended by the patient’s physician.

    To learn more about the criteria for hospice eligibility or to schedule a consultation, please contact Crossroads using the blue Help Center bar on this page for more information on how we can help provide support to individuals with dementia and their families.

    Exercise Is Just As Good For Your Brain As It Is For Your Body

    Aerobic exercise raises your heart rate and increases blood flow to your brain. As your increased breathing pumps more oxygen into your bloodstream, more oxygen is delivered to your brain. This leads to neurogenesisor the production of neuronsin certain parts of your brain that control memory and thinking. Neurogenesis increases brain volume, and this cognitive reserve is believed to help buffer against the effects of dementia.

    It has been noted that exercise promotes the production of neurotrophins, leading to greater brain plasticity, and therefore, better memory and learning. In addition to neurotrophins, exercise also results in an increase in neurotransmitters in the brain, specifically serotonin and norepinephrine, which boost information processing and mood.

    The Gems Of Caregiving: Teepa Snow, Dementia Expert

    Lewy body dementia is a common brain disorder that impairs a person’s ability to do everyday activities. Although the disorder occasionally runs in families, most cases occur spontaneously. Protein deposits made of alpha-synuclein form “Lewy bodies” in brain tissue that are identified microscopically and are are characteristic of the disease. The Lewy bodies accumulate in different areas of the brain, including the cerebral cortex, and affect the brain’s ability to function properly. LBD affects cognition, sleep, mood, behavior, and movement. Hallucinations may also be a component of LBD. Aspects of the condition mimic symptoms of Parkinson’s disease.

    The diagnosis of LBD may be difficult because early symptoms resemble those of Alzheimer’s disease and Parkinson’s. Although there is no cure for LBD, treatment can help manage symptoms.

    Does Brain Size Matter

    Obviously, not all people have the same size brain. Some are larger, and some are smaller. You might find yourself wondering if brain size might be linked to characteristics such as disability or intelligence.

    Researchers have found that in some cases brain size can be linked to certain diseases or developmental conditions.

    For example, autistic children tend to have bigger brains than non-autistic children. The hippocampus tends to be smaller in elderly adults suffering from Alzheimerâs disease. This area of the brain is strongly associated with memory.

    What about intelligence? The answer to that question depends largely upon who you ask. According to one analysis of many studies that looked at this issue by Michael McDaniel of Virginia Commonwealth University, bigger brains were correlated with higher intelligence.

    Not all researchers necessarily agree with McDanielâs conclusions. Such studies also raise important questions about how we define and measure intelligence, whether we should account for relative body size when making such correlations, and what parts of the brain we should be looking at when making such determinations.

    It is also important to note that when looking at individual differences among people, brain size variations are relatively small. Other factors that may influence or play a pivotal role include the density of neurons in the brain, social and cultural factors, and other structural differences inside the brain.

    Tips For Managing Dementia End

    Because individuals with advanced dementia will often have difficulty communicating, it is important that caregivers keep a close eye on their loved one for signs of pain or discomfort. These signs may include moaning or yelling, restlessness or an inability to sleep, grimacing, or sweating. This may also signal that its time to call hospice or a palliative care team to help with the pain management.

    If an individual with end-stage dementia is having trouble sitting up without assistance, hospice can provide a hospital bed or other equipment to lift their head.

    Perhaps the hardest thing for families is when a loved one with dementia is no longer able to eat or swallow. Because an individual with dementia is unable to understand the benefits of feeding tubes or IV drips, they will often be incredibly distressed and attempt to remove them, causing added pain and risk of infection. Instead, focusing on keeping the individual comfortable. Supporting them with mouth care to prevent their mouth from becoming dry will allow them to make their final transition in peace.
