Dementia and Alzheimer’s: What Are the Differences?

Alzheimer’s disease and dementia are not the same. There are many different types of dementia, but the most common is Alzheimer’s disease and dementia with Lewy bodies.

The most frequent form of dementia is Alzheimer’s disease. Alzheimer’s disease progresses over time and affects memories, language, and thought.

When it comes to Alzheimer’s and dementia, you’re more likely to get it as you become older. Despite the fact that dementia and Alzheimer’s disease are the two most common afflictions in those over 65, none is considered a normal component of aging.

Both illnesses can have similar symptoms, but it’s critical to tell them apart for treatment and management. Learn more about distinctions in the next paragraphs.

What Does the Term “Dementia” Mean

More than 55 million individuals worldwide are estimated to have dementia, according to the World Health Case study provides Source.

Dementia is a set of symptoms, not a medical condition. Undiagnosed symptoms are grouped together as syndromes.

Memory and thinking are two of the cognitive functions that are affected by dementia. Alzheimer’s disease is the most common cause, but there are many more.

Dementia can manifest itself in a variety of ways. This type of dementia is called “mixed.” The symptoms of two or more forms of dementia are present in people with mixed dementia.

An autopsy is required to definitively determine if a patient has mixed dementia.

Dementia deteriorates a person’s capacity for self-care and independence as the disease progresses. It’s a leading cause of disability among the elderly, and it has a significant impact on the relatives and carers of those affected.

There will be a three-fold increase in dementia cases over the next 30 years, making it the world’s fifth biggest cause of death.

Symptoms of Dementia

Early symptoms Progressive symptoms Advanced symptoms
• occasional forgetfulness
• losing track of time
• losing your way in familiar settings
• frequent forgetfulness
• more confusion
• repetitive questioning
• poor hygiene
• poor decision making
• unable to care for yourself
• trouble with time
• difficulty remembering familiar people and places
• change in behavior
• depression
• aggression

Dementia’s early symptoms, which might be subtle, are often overlooked. In many cases, forgetfulness is the first sign of Alzheimer’s disease or other forms of dementia.

Dementia patients have a hard time keeping track of their time and frequently get lost in familiar places.

Forgetting and confusion become more common as dementia advances. The ability to remember names and faces diminishes. Taking care of one’s own needs becomes an issue.

Dementia can be clearly seen in a person’s repetitive questions, poor hygiene, and difficulty making decisions.

Dementia patients can no longer take care of themselves at even the latest stages of the disease. They’ll have a harder time maintaining track of the time and remembering familiar faces and places.

Their moods can fluctuate, ranging from elation to rage to melancholy to aggressiveness.

Reason of Dementia

Dementia is more common as you become older. It is a side effect of brain injury. Degenerative disorders including Alzheimer’s, Parkinson’s, and Huntington’s are among the many possible causes of dementia.

Dementia damages a particular set of neurons depending on the underlying reason.

More than half of all forms of dementia are caused by Alzheimer’s disease.

  • infections, such as HIV
  • vascular diseases
  • stroke
  • depression
  • chronic drug use

Older African Americans have twice the risk of dementia than non-Hispanic whites, according to the Centers for Disease and Promotion (CDC) (Trusted Source).

Dementia is 1.5 times as common among Hispanics than in non-Hispanic whites. One explanation for these figures is the existence of structural injustices and obstacles to healthcare for underserved groups in our society.

Alzheimer’s and Other Forms of Dementia

Aside from Alzheimer’s, there are numerous other possible causes of dementia.

Vascular Dementia

This type of dementia is commonly linked to attacks or the accumulation of plaque in the arteries and results from an obstruction of blood flow to the brain. The onset of symptoms might be gradual or rapid, depending on the individual.

Dementia accompanied by Lewy limbs

The protein deposits in your nerves that interrupt electrical signals create dementia with Lewy bodies, a degenerative condition. Symptoms such as altered thinking, disorientation, and alterations in gait are possible.

Dementia from Parkinson’s Disease

After a year or longer of being diagnosed with Parkinson’s, many Parkinson’s sufferers experience cognitive decline.

People with Parkinson’s disease may experience dementia 50 to 80% percent of the time, with onset occurring after an average of roughly 10 years.

Frontotemporal dementia

Those with frontotemporal dementia have a loss of brain function in the area of the brain near their forehead or behind their ears, which is known as frontotemporal dementia. The first indications of frontotemporal dementia include behavioral changes, according to the Alzheimer’s Association.

Posterior Cortical Atrophy

There is a progressive degeneration of the cortex in the back of the brain’s outer layer known as posterior cortical atrophy. Problems with visual skills such as reading or detecting motion are among the most common symptoms.

The Condition known as Creutzfeldt-Jakob Syndrome

Every year, approximately 350 Americans are diagnosed with Creutzfeldt-Jakob disease, a rare infectious disease.

Muscle coordination and behavioural changes are among the first symptoms of dementia caused by Alzheimer’s disease. Approximately 70% of people die within a year of their birth.

Alzheimer’s Disease is an Illness That Affects the Brain

There are many signs of dementia, but Alzheimer’s is a disease of the brain that affects memory and concentration in a precise and gradual way over time. There is no known cause and no known remedy.

Symptoms of Alzheimer’s typically begin in adults over the age of 65, despite the fact that younger people can develop the disease.

Alzheimer’s disease and its aftereffects on the brain

Alzheimer’s disease is characterized by the death of brain cells and the breakdown of connections between brain cells. Plaques and tangles, which are aberrant protein aggregates in the brain, are one of the disease’s defining signs.

Neuronal communication can be impeded by plaques, which are protein-rich clumps. The death of brain health cells is caused by proteins that tangle together.

There is a noticeable shrinkage of the brain in the latter stages of Alzheimer’s. Symptoms may not appear for a decade or more after brain changes have taken place.

As long as a person is alive, it is impossible to accurately identify Alzheimer’s disease. When the brain is inspected under a microscope when in an autopsy, the diagnosis can be verified. Specialists, on the other hand, have a 90% success rate in correctly diagnosing patients.

Symtoms of Alzheimer’s Vs. Dementia

Alzheimer’s and dementia symptoms may resemble one another, but they can sometimes differ.

Both of these disorders can lead to a variety of symptoms.

  • a decline in the ability to think
  • memory impairment
  • communication impairment

The symptoms of Alzheimer’s include:

  • difficulty remembering recent events or conversations
  • apathy
  • depression
  • impaired judgment
  • disorientation
  • confusion
  • behavioral changes
  • difficulty speaking, swallowing or walking in advanced stages of the disease

Some of these symptoms may be present in different forms of dementia, however, a differential diagnosis can be made based on the presence or absence of other symptoms.

Alzheimer’s and Lewy body dementia (LBD) has many of the same later symptoms. While patients with LBD are more prone to have first indications including visual hallucinations, balance issues, and sleep issues, this is not the case for everyone with the disorder.

In the early phases of Parkinson’s and Huntington’s disease dementia, people are more prone to suffer involuntary movement.

What’s the Difference Between Alzheimer’s and Other Forms of Dementia in Terms of Treatment?

Many therapies for dementia and Alzheimer’s disease will overlap, depending on the underlying cause and kind of dementia.

Alzheimer’s Treatment

  • medications for behavioral changes, such as antipsychotics
  • medications for memory loss, which include cholinesterase inhibitors donepezil (Aricept) and rivastigmine (Exelon), and memantine (Namenda)
  • alternative remedies that aim to boost brain function or overall health, such as coconut oil or fish oil
  • medications for sleep changes
  • medications for depression

Dementia and Alzheimer's

Dementia treatment

Treating the underlying illness that causes dementia may be beneficial in some circumstances. Dementia induced by the following conditions is most likely to be treated:

  • drugs
  • tumors
  • metabolic disorders
  • hypoglycemia

Dementia is almost often irreversible. In many cases, though, treatment is possible. It is possible to control dementia with the correct medication.

What causes dementia will have an impact on how we treat it. Cholinesterase inhibitors, for example, are commonly used to treat Parkinson’s disease, Alzheimer’s disease, and other forms of dementia.

Averting further injury to the brain’s vascular system and preventing a stroke are the main goals of vascular dementia treatment.

Dementia patients can also benefit from home health aides as well as other caretakers’ support. As the disease advances, an assisted living home and nursing home may be required.

People with Dementia Have a Better Prognosis Than Those With Alzheimer’s Disease

Dementia sufferers’ future depends solely on the underlying reason. Dementia caused by Parkinson’s disease can be controlled with medication, but the disease itself cannot be halted or even slowed down with treatment.

However, vascular dementia might be slowing down, but it still cuts down the lifespan of the patient. Dementia can be reversed in some cases, but most are irreversible and would only worsen with time.

Alzheimer’s is a fatal disease for which there is no cure at this time. Stages one, two, and three all have varying lengths of time.

After being diagnosed with Alzheimer’s, people over the age of 65 should expect to survive between four and eight years. It is possible to live for up to 20 years.

If you have any suspicions that you may be suffering from dementia or Alzheimer’s disease, you should consult a physician.

The sooner you begin treatment, the better equipped you will be to deal with your symptoms. If you’re interested in reading more articles like this, please visit TheActiveNews.Com.
