Definition of dementia

Dementia may be a decline in cognitive function. To be considered dementia, mental impairment must affect a minimum of two brain functions. Dementia may affe

  • Memory
  • Thinking
  • Language
  • Judgment
  • Behavior

Dementia isn’t a disease. It’s going to be caused by a spread of illnesses or injuries. Mental impairment may range from mild to severe. It’s going to also cause personality changes.

Some dementias are progressive. This suggests they worsen over time. Some dementias are treatable or maybe reversible. Some specialists confine the term dementia to irreversible mental deterioration.

Dementia symptoms

In its beginning phases, dementia can cause indications, for example:

  • Not coping well with change. You’ll have a tough time accepting changes in schedules or environment.
  • Subtle changes in short-term memory-making. You or a beloved can remember the events of 15 years ago love it was yesterday, but you can’t remember what you had for lunch.
  • Reaching for the proper words. Word recollection or association could also be harder.
  • Being repetitive. You’ll ask an equivalent question, complete an equivalent task, or tell an equivalent story multiple times.
  • Confused sense of direction. Places you once realized well may now feel foreign. You’ll also struggle with driving routes you’ve taken for years because it does not look familiar.
  • Struggling to follow storylines. You’ll find following a person’s story or description difficult.
  • Changes in mood. Depression, frustration, and anger aren’t uncommon for people with dementia.
  • Loss of interest. Apathy may occur in people with dementia. This includes losing interest in hobbies or activities that you simply once enjoyed.
  • Confusion. People, places, and events may not feel familiar. You would possibly not remember people that know you.
  • Difficulty completing everyday tasks. You’ll struggle to recall the way to do tasks you’ve finished a few years.

Memory problems aren’t always a symbol of dementia. These 10 early signs may indicate you’re experiencing a decline in memory and capacity.

Stages of dementia

In most cases, dementia is dynamic, getting worse over time. Dementia progresses differently in everyone. However, most of the people experience symptoms of the subsequent stages of dementia:

Mild cognitive impairment

Older individuals may develop mild cognitive impairment (MCI) but may never reach dementia or other mental impairment. People with MCI commonly experience forgetfulness, trouble recalling words, and STM problems.

Mild dementia

At this stage, people with mild dementia could also be ready to function independently. Symptoms include:

  • Short-term memory lapses
  • Personality changes, including anger or depression
  • Misplacing things or forgetfulness
  • Difficulty with complex tasks or problem-solving
  • Struggling to precise emotions or ideas

Moderate dementia

At this stage of dementia, people impacted may have assistance from a beloved or care provider. That’s because dementia may now interfere with daily tasks and activities. Symptoms include:

  • Poor judgment
  • Increasing confusion and frustration
  • Memory loss that reaches further into the past
  • Needing help with tasks like dressing and bathing
  • Significant personality changes

Severe dementia

At this late stage of dementia, the mental and physical symptoms of the condition still decline. Symptoms include:

  • Inability to take care of bodily functions, including walking and eventually swallowing and controlling bladder
  • Inability to speak
  • Requiring full-time assistance
  • Increased risk for infections

People with dementia will advance through the phases of dementia at various rates. Understanding the stages of dementia can assist you to steel oneself against the longer term.

What causes dementia?

There are many causes of dementia. Generally, it results from the degeneration of neurons (brain cells) or disturbances in other body systems that affect how neurons function.

A few conditions can cause dementia, including ailments of the brain. The foremost common such causes are Alzheimer’s disease and vascular dementia.

Neurodegenerative means neurons gradually cease to function or function inappropriately and eventually die.

This affects the neuron-to-neuron connections, called synapses that are how messages are passed along in your brain. This disconnect may result during a range of dysfunction.

Some of the more typical reasons for dementia include:

Neurodegenerative diseases
  • Alzheimer’s disease
  • Parkinson’s disease with dementia
  • Vascular dementia
  • Medication side effects
  • Chronic alcoholism
  • Certain tumors or infections of the brain

Another cause is front temporal lobar degeneration, which may be a blanket term for a variety of conditions that cause damage to the frontal and temporal lobes of the brain. They include:

  • Front temporal dementia
  • Pick’s disease
  • Supranuclear palsy
  • Corticobasal degeneration
Other causes of dementia

Dementia can also be caused by other conditions, including:

  • Structural brain disorders, like normal-pressure hydrocephalus and subdural hematoma
  • Metabolic disorders, like hypothyroidism, vitamin B-12 deficiency, and kidney and liver disorders
  • Toxins, like lead

Some of these dementias could also be reversible. These treatable reasons for dementia may turn around symptoms if they’re gotten early enough. This is often one of the various reasons why it’s important to ascertain your doctor and obtain a medical workup as soon as symptoms develop.

Types of dementia

Most cases of dementia are a symbol of a selected disease. Different diseases cause different types of dementia. The foremost common sorts of dementia include:

  • Alzheimer’s disease. The foremost common sort of dementia, Alzheimer’s disease makes up 60 to 80 percent of dementia cases.
  • Vascular dementia. This sort of dementia is caused by reduced blood flow within the brain. It’s going to be the results of plaque buildup in arteries that feed blood to the brain or a stroke.
  • Lewy body dementia. Protein stores in nerve cells keep the brain from sending synthetic signals. This leads to lost messages, delayed reactions, and amnesia.
  • Parkinson’s disease. Individuals with advanced Parkinson’s disease may develop dementia. Symptoms of this particular sort of dementia include problems with reasoning and judgment, also as increased irritability, paranoia, and depression.
  • Frontotemporal dementia. Several sorts of dementia fall under this category. They’re each suffering from changes within the front and side parts of the brain. Symptoms include difficulty with language and behavior, also because of the loss of inhibitions.

Other sorts of dementia exist. However, they’re less common. One sort of dementia occurs in just 1 in 1 million people. Learn more about this rare sort of dementia et al.

Dementia testing

No single test can confirm a dementia diagnosis. Instead, a health care provider will use a series of tests and exams. These include:

  • a thorough medical record
  • a careful physical exam
  • Laboratory tests, including blood tests
  • A review of symptoms, including changes in memory, behavior, and brain function
  • A case history

Doctors can determine if you or a beloved is experiencing symptoms of dementia with a high degree of certainty. However, they’ll not be ready to determine the precise sort of dementia. In many cases, symptoms of dementia types overlap. That creates distinguishing between two types difficult.

Some health care providers will diagnose dementia without specifying the sort. Therein case, you’ll wish to ascertain a doctor that focuses on diagnosing and treating dementia. These doctors are called neurologists. Some geriatricians also concentrate on this sort of diagnosis.
