What mental illness causes excessive speaking


Dementia is a gradual decline in mental abilities, with memory, reasoning, judgment and learning being impaired.
  • Typical symptoms include memory loss, problems speaking and performing activities, personality changes, disorientation, and aggressive or inappropriate behavior.

  • The symptoms progress until those affected become dependent, which makes them completely dependent on others.

  • The doctor makes the diagnosis based on symptoms and the results of a physical exam and a mental health exam.

  • Blood tests and imaging tests will be used to determine the cause.

  • Treatment focuses on maintaining mental functions for as long as possible and supporting those affected as they worsen.

Dementia mainly occurs in people over the age of 65. Dementia, and especially the aggressive behavior that is often associated with it, is the reason for 50 percent of the admissions to old people's homes. However, dementia is a disease and not part of normal aging. Many people over the age of 100 do not have dementia.

Dementia is different from delirium, which is characterized by difficulty concentrating, disorientation, inability to think clearly, and fluctuations in attention.

  • Dementia mainly affects memory and delirium affects attention.

  • Dementia usually develops gradually without a specific point in time. Delirium begins suddenly and often at a specific time.

Age-related changes in the brain (also called forgetfulness of old age) lead to certain disorders of the short-term memory and a decrease in the ability to learn. In contrast to dementia, these changes are normal in old age and do not interfere with independent living. Such forgetting of old age is not necessarily a sign of dementia or an early stage of Alzheimer's disease. However, the earliest symptoms of dementia are very similar.

A mild cognitive disorder causes greater memory loss than old age forgetfulness. It can also affect speaking, thinking, and judgment. However, like old age forgetfulness, it does not affect the independent lifestyle. Up to half of people with mild cognitive impairment will develop dementia within three years.

At a dementia the mental abilities deteriorate much more drastically and are more and more lost over time. While older people tend to misplace things and remember details poorly, dementia sufferers may forget events completely. People with dementia find it difficult to cope with normal everyday tasks such as driving a car, cooking or keeping accounts.

Especially in the elderly you can depressions resemble dementia, but they can usually be distinguished. People with depression tend to sleep and eat little. People who suffer from dementia usually eat and sleep normally until the disease progresses. People with depression can often complain loudly about memory loss, but rarely forget important current events or personal matters. In contrast, people with dementia are unaware of their mental disorder and often deny their memory loss. After treatment for depression, the sufferer's mental abilities are restored. However, many people suffer from depression and dementia. In such cases, depression treatment can improve mental functions, but not restore them entirely.

Some types of dementia (such as Alzheimer's disease) have low levels of acetylcholine in the brain. Acetylcholine is a chemical messenger (called a neurotransmitter) that helps nerve cells communicate with each other. Acetylcholine supports memory, the ability to learn and concentrate, and helps control many organs. Other changes are taking place in the brain, but it is unclear whether these are the cause or the result of dementia.

Dementia usually occurs as a brain disease without any other cause (called primary brain disease), but it can be triggered by many disorders.

Common causes of dementia

The most common form of dementia is that

About 60 to 80 percent of older people with dementia suffer from Alzheimer's disease.

Other common types of dementia include the

Many people have more than one of these types of dementia (called mixed dementia).

Other conditions that can cause dementia

Dementia can be caused by:

Reversible dementia

Most of the diseases that cause dementia are irreversible, but some can be treated and make the dementia reversible. (Some professionals only use the term dementia for progressive, irreversible diseases, and use terms such as encephalopathy or cognitive loss when the dementia can be partially reversed.) These forms of dementia can often be cured with treatment, provided the brain has not become too strong affected. If the brain damage is more significant, treatment usually cannot undo the damage, but it can prevent new damage.

Reversible dementia is caused by:

A subdural hematoma (a pool of blood between the outer and middle layers of tissue that cover the brain) occurs when one or more blood vessels rupture, usually due to a brain injury. Such injuries can be minor and may not be recognized. Subdural hematomas can cause a slow decrease in mental function, which treatment may reverse.

Other diseases


Many medicines can temporarily cause or worsen symptoms of dementia. Some of these medicines are available without a prescription (without a prescription). Sleep pills (which are sedatives), cold medicines, sedatives, and some antidepressants are common examples.

Alcohol consumption, even in moderation, can make dementia worse, and most professionals recommend abstaining from alcohol altogether.


Progression of symptoms of dementia

In people with dementia, mental functions usually deteriorate within two to ten years. However, depending on the cause, dementia progresses at different speeds:
