Which Of The Following Symptoms Is Suggestive Of Alzheimer Disease

Symptoms And Signs Of Alzheimer Disease

What are the Stages of Alzheimers Disease? Symptoms of Late- and End-Stage Alzheimers Disease

Patients with Alzheimer disease have symptoms and signs of dementia.

The most common first manifestation of Alzheimer disease is

  • Loss of short-term memory

Other cognitive deficits tend to involve multiple functions, including the following:

  • Impaired reasoning, difficulty handling complex tasks, and poor judgment

  • Language dysfunction

  • Visuospatial dysfunction

Alzheimer disease progresses gradually but may plateau for periods of time.

Behavior disorders are common.

Diagnosis Of Early Onset Alzheimer Disease

“The neurologist diagnosed conversion disorder;. I should not have believed that. We went to counseling sessions for a year but nothing happened.”Caregiver.

Families with eFAD tell stories of being misdiagnosed because their doctors had ruled out the possibility of AD in people who are so young , or simply did not consider it seriously. “My brother’s first symptoms were personality changes, weight gain, loss of physical coordination, and then short-term memory loss. We thought those signs would be enough for him to be diagnosed correctly given that his mother and uncle also had had early onset AD. But still it took nearly two years of neurological assessments before the doctors would give my brother his diagnosis,” an unaffected sibling said. Ironically, AD specialists say that provided the doctor is attuned to AD occurring in younger people, diagnosing eFAD can actually be easier than diagnosing LOAD. Elderly patients are more likely to have other medical conditions that can cause dementia, making diagnosis trickier. For example, cardiovascular disease and diabetes are very common in older people, and can cause symptoms that overlap with AD. In younger patients, this is less likely to be the case. A main challenge in diagnosing eFAD is to distinguish it from other types of dementia that begin in middle age, for example, frontotemporal dementias such as Pick disease.

Alzheimer’s Disease Is A Type Of Dementia

Alzheimer’s disease is a type of dementia, which is a term used to describe a range of symptoms that affect a person’s memory, thinking, and reasoning to the point they interfere with daily tasks. Alzheimer’s disease accounts for up to 80% of cases of dementia. In mild dementia, the loss of cognitive skills only slightly affects a person’s daily life, while in severe dementia a person is no longer able to function independently and becomes totally reliant on others for care.

Alzheimer’s Disease Is Diagnosed By A Blood Test

Alzheimer’s disease cannot be diagnosed with a blood test, or any one single test. However, blood tests, urine tests, and imaging tests, such as computed tomography , magnetic resonance imaging , or positron emission tomography may be performed to rule out other conditions that may be causing the symptoms. The diagnosis of Alzheimer’s disease is often made by a thorough medical history, along with tests on memory, language, problem solving, counting, and attention. These tests are often repeated so doctors can see any changes that happen over time.

What Is Known About Alzheimers Disease

World Alzheimer

Scientists do not yet fully understand what causes Alzheimers disease. There likely is not a single cause but rather several factors that can affect each person differently.

  • Age is the best known risk factor for Alzheimers disease.
  • Family historyresearchers believe that genetics may play a role in developing Alzheimers disease. However, genes do not equal destiny. A healthy lifestyle may help reduce your risk of developing Alzheimers disease. Two large, long term studies indicate that adequate physical activity, a nutritious diet, limited alcohol consumption, and not smoking may help people. To learn more about the study, you can listen to a short podcast.
  • Changes in the brain can begin years before the first symptoms appear.
  • Researchers are studying whether education, diet, and environment play a role in developing Alzheimers disease.
  • There is growing scientific evidence that healthy behaviors, which have been shown to prevent cancer, diabetes, and heart disease, may also reduce risk for subjective cognitive decline. Heres 8 ways.

Initial History And Functional Assessment

When dementia is suspected, physicians should obtain a history from the patient and from a family member or caregiver, because patients with dementia often do not have insight into their deficits. The history should include specifics of cognitive deficit, time of onset, and speed of progression. It is imperative to assess the extent of impairment in instrumental activities of daily living, which include managing money and medications, shopping, housekeeping, cooking, and transportation. In the early stages of dementia, instrumental activities of daily living that require calculation and planning, such as balancing a check-book or filling a pillbox, are often the first to become impaired. Basic activities of daily living, such as dressing, eating, toileting, and grooming, are generally intact in early dementia and do not become impaired until later in the disease progression.

Although the physical examination is not usually affected in patients with Alzheimer disease, abnormalities can give clues about less common types of dementia. Focal deficits from a previous stroke are common in patients with vascular dementia. Parkinsonism is seen in patients during the later stages of dementia with Lewy bodies. Table 1 lists key findings from the patient history and physical examination that may accompany cognitive dysfunction, and the suggested diagnoses.

Key Findings and Suggested Diagnoses in Patients with Cognitive Dysfunction

Pathology Of Alzheimers Disease

Macroscopic features

Fig. 1

Gross Anatomy of Alzheimers Brain. Lateral view of an Alzheimers brain can show widening of sulcal spaces and narrowing of gyri compared to a normal brain. This may be more readily observed in coronal sections as indicated by the arrowheads, and this atrophy is often accompanied by enlargement of the frontal and temporal horns of the lateral ventricles as highlighted by the arrows. Additionally, loss of pigmented neurons in the locus coeruleus is commonly observed in the pontine tegmentum as shown with the open circle. None of these features is exclusive to Alzheimers disease

Microscopic features

The definitive diagnosis of AD requires microscopic examination of multiple brain regions employing staining methods that can detect Alzheimer type neuropathologic change , with diagnosis based upon the morphology and density of lesions and their topographic distribution. Several of the brain regions that are vulnerable to Alzheimer type pathologic change are also vulnerable to other disease processes, such as -synucleinopathy and TDP-43 proteinopathy. Mixed pathology is common. Indeed in the Mayo Clinic Brain Bank from 2007 to 2016 , the majority of AD cases had coexisting non-Alzheimer pathologies, and comorbidities increased in frequency with age. Furthermore, when the original clinical diagnoses were examined for cases with pure AD pathology, it is clear that a number of clinical syndromes can masquerade as Alzheimers disease.

Normal Aging Vs Dementia

While some mild changes in cognition are considered a normal part of the aging process, dementia is not. Normal age-related declines are subtle and mostly affect the speed of thinking and attentional control. In abnormal aging, declines in cognition are more severe and may include other thinking abilities, such as rapid forgetting or difficulties navigating, solving common problems, expressing oneself in conversation or behaving outside of social rules. Abnormal aging can also include the motor system resulting in excessive tripping, falls or tremor. Often it is difficult to determine exactly when a person should be concerned with cognitive changes they may be experiencing. Symptoms vary from person to person what is normal for one person may not be normal for another. This contributes to the challenges clinicians face when determining whether what someone is experiencing is a significant for them or within normal expectations.

Definitive diagnosis is outlined by brain tests and metabolic tests too. Thyroid tests and vitamin tests are top on the list. EEG is even done to study sleep patients to know whether the patient is suffering from REM and NREM sleep patterns.

These too are non-curable disease formats. Their adversity is reduced by treating a patient with symptomatic medicines. This will provide a bit of relief in ones life. Behavioral intervention and physical therapy are coupled with medical treatment for the longevity of life.

How Is Alzheimers Disease Treated

Medical management can improve quality of life for individuals living with Alzheimers disease and for their caregivers. There is currently no known cure for Alzheimers disease. Treatment addresses several areas:

  • Helping people maintain brain health.
  • Managing behavioral symptoms.
  • Slowing or delaying symptoms of the disease.

How Is Alzheimer’s Disease Diagnosed And Evaluated

No single test can determine whether a person has Alzheimer’s disease. A diagnosis is made by determining the presence of certain symptoms and ruling out other causes of dementia. This involves a careful medical evaluation, including a thorough medical history, mental status testing, a physical and neurological exam, blood tests and brain imaging exams, including:

How Is Alzheimer’s Different From Other Forms Of Dementia

Alzheimer’s disease is distinguished from other forms of dementia by characteristic changes in the brain that are visible only upon microscopic examination during autopsy. Brains affected by Alzheimer’s disease often show presence of the following:

  • Fiber tangles within nerve cells

  • Clusters of degenerating nerve endings

Another characteristic of Alzheimer’s disease is the reduced production of certain brain chemicals necessary for communication between nerve cells, especially acetylcholine, as well as norepinephrine, serotonin, and somatostatin.

Support For Family And Friends

What Are the Stages of Alzheimers Dementia?

Currently, many people living with Alzheimers disease are cared for at home by family members. Caregiving can have positive aspects for the caregiver as well as the person being cared for. It may bring personal fulfillment to the caregiver, such as satisfaction from helping a family member or friend, and lead to the development of new skills and improved family relationships.

Although most people willingly provide care to their loved ones and friends, caring for a person with Alzheimers disease at home can be a difficult task and may become overwhelming at times. Each day brings new challenges as the caregiver copes with changing levels of ability and new patterns of behavior. As the disease gets worse, people living with Alzheimers disease often need more intensive care.

What Is Alzheimer’s Disease

Alzheimer’s disease is the most common cause of dementia, a loss of brain function that affects memory, thinking, language, judgment and behavior. In Alzheimer’s disease, large numbers of neurons;stop functioning, lose connections with other neurons, and die.

Irreversible and progressive, Alzheimer’s disease slowly destroys memory and thinking skills and, eventually, the ability to carry out the simplest tasks of daily living.

Although the cause of Alzheimer’s disease is unknown, scientists believe that a build-up of beta-amyloid plaques;and neurofibrillary tangles;in the brain are associated with the disease.

The stages of the disease typically progress from mild to moderate to severe. Symptoms usually develop slowly and gradually worsen over a number of years; however, progression and symptoms vary from person to person. The first symptom of Alzheimer’s disease usually appears as forgetfulness.

Mild cognitive impairment is a stage between normal forgetfulness due to aging and the development of Alzheimer’s disease. People with MCI have mild problems with thinking and memory that do not interfere with everyday activities. Not everyone with MCI develops Alzheimer’s disease.

Other early symptoms of Alzheimer’s include language problems, difficulty performing tasks that require thought, personality changes and loss of social skills.

People with severe Alzheimer’s disease are unable to recognize family members or understand language.

What To Do If You Suspect Alzheimers Disease

Getting checked by your healthcare provider can help determine if the symptoms you are experiencing are related to Alzheimers disease, or a more treatable conditions such as a vitamin deficiency or a side effect from medication. Early and accurate diagnosis also provides opportunities for you and your family to consider financial planning, develop advance directives, enroll in clinical trials, and anticipate care needs.

What Is Alzheimers Disease

  • Alzheimers disease is the most common type of dementia.
  • It is a progressive disease beginning with mild memory loss and;possibly leading to loss of the ability to carry on a conversation and respond to the environment.
  • Alzheimers disease involves parts of the brain that control thought, memory, and language.
  • It can seriously affect a persons ability to carry out daily activities.

The Patient Forgets Important Events That Have Happened Only Recently

What The New Alzheimer’s Disease Drug Means For Patients

It is worth paying attention if a relative suddenly forgets an important conversation that has taken place very recently, or some other recent and important event.

Of course, forgetfulness sometimes affects everyone, but one of the main prerequisites that helps to distinguish Alzheimers patients they most rarely remember that they have forgotten something.

Why Early Detection Can Be Difficult

Alzheimers disease usually is not diagnosed in the early stages, even in people who visit their primary care doctors with memory complaints.

  • People and their families generally underreport the symptoms.
  • They may confuse them with normal signs of aging.
  • The symptoms may emerge so gradually that the person affected doesnt recognize them.
  • The person may be aware of some symptoms but go to great lengths to conceal them.

Recognizing symptoms early is crucial because medication to control symptoms is most effective in the early stages of the disease and early diagnosis allows the individual and his or her family members to plan for the future. If you or a loved one is experiencing any of the following symptoms, contact a physician.

Significant Exacerbation Of The Disease

The ability to perform daily life activities is completely lost, and a person depends on a caregiver. In the last stage of the disease, the disease is no longer curable, so the patient is close to death.

At this stage, the patient may have lost the ability to respond to the environment or communicate, although it is possible that the person may still express a few words.

They also lose gut and bladder control. In this condition, the patient is no longer aware of his illness and needs help with almost all daily activities.

Because the disease results in the loss of a persons physical function because of brain cell death, the patient may not swallow saliva or food.

Added Research On The Way

We discussed that memory disorders are thoroughly catered by symptomatic treatments. But as scientific studies and researches are advancing daily, there is a more innovative and straightforward approach to this. Drug-induced dementias are more likely to be reversed while progressive dementias are made to slow down in its process.

Alzheimer disease and dementia both can be progressed to slower deterioration rate via DBS. Deep brain stimulation is a device like a pacemaker. Just like a pacemaker is used to elicit the SA node, these devices elicit deep brain portions to create places for memory holdings and integrations. Synaptic transmissions are accommodated by sending electrical signals to specific brain areas.

The new medicinal approach has also come up with the latest advancements. There are certain protein cutting drugs on their way which are going to destroy plaque formation and neurofibrillary tangles that are formed. This will lead a path to the most advanced evaluative treatment for Alzheimers.

An MRI case study from a patient with COVID-19 with acute onset of anosmia in Iran reported normal nasal mucosa and normal volume of olfactory bulbs bilaterally . Dysfunction of smell and taste have been widely reported in patients with COVID-19 in European communities . Lechien and colleagues found that among 417 patients with mild to moderate COVID-19, 85.6% reported having olfactory dysfunction and 88.0% had gustatory dysfunction . Among 59 patients hospitalized with COVID-19 in a hospital in Italy, 33.9% reported having smell or taste impairment and 18.6% reported having both . Among 202 patients with mild COVID-19 symptoms in another hospital in Italy, 64.4% had impaired sense of smell or taste . However, among 214 patients hospitalized in China , with severe or non-severe COVID-19 symptoms, only 5.1% and 5.6% had smell or taste impairment; these impairments were more prevalent among patients with mild COVID-19 than those with severe COVID-19 .

Symptoms To Watch For

  • Getting lost in familiar places
  • Repetitive questioning
  • Repeated falls or loss of balance
  • Personality changes
  • Changes in diet/eating habits
  • Increased apathy
  • Changes in language abilities, including comprehension

The progression of cognitive deficits observed in conditions such as Alzheimers disease may be accelerated in the few years immediately preceding the diagnosis. Accelerated cognitive decline may not occur until events, like a life stressor or other illness , reach a threshold where the brain can no longer compensate for damage. Thus, it is important to get regular medical check-ups to monitor the extent and severity to which someone may be experiencing cognitive decline. Independent living should not be compromised during normal aging, unlike the transition to a neurodegenerative condition.

CARE ARRANGEMENTS

In terms of care arrangements for Lewy Body Dementia;patients, there are generally two types of options that the patients friends and family can opt for:;in-home care;or;out-home care.;

During the initial stages, while the patient is still able to function independently, most people may prefer to remain at home, where they are most familiar with their surroundings.

After initial diagnosis, the primary caregiver may still be able to handle the tasks of looking after the patient. But as the symptoms progress to the early and middle stages, they can opt for in-home care arrangements. There are several types available in this category:

    • Companion services to help with supervision and recreational activities.
    • Personal carers to help with various personal care tasks such as bathing, dressing, eating, and exercising.
    • Homemaker services to help with housekeeping, cooking, or shopping.
    • Medical carers to help with medical needs, physical, and/or mental therapies

Hospice Care;and;Geriatric Psychiatric Facilities;are two lesser talked about short-term arrangements for patients with dementia. These systems assist with end of life comfort measures and medication rebalancing , both of which are crucial to maintaining the patients dignity and safety for them and their caregivers.
