• memory problems, particularly remembering recent events.
• increasing confusion.
• reduced concentration.
• personality or behaviour changes.
• apathy and withdrawal or depression.
• loss of ability to do everyday tasks.

Can a fall accelerate dementia?

People who’ve had a severe head trauma have a greater risk of Alzheimer’s disease. Several large studies found that in people age 50 years or older who had a traumatic brain injury (TBI), the risk of dementia and Alzheimer’s disease increased.

What medical conditions cause confusion?

Health problems that can cause confusion or decreased alertness include:

• Infections, such as a urinary tract infection, respiratory infection, or sepsis.
• Alzheimer’s disease.
• Asthma or COPD, which cause a decrease in the amount of oxygen or an increase in the amount of carbon dioxide in the blood.

What causes dementia to progress quickly?

Depression. Thyroid problems, such as hypothyroidism. Additional neurological conditions. Autoimmune neurological disorders and paraneoplastic disorders, which are conditions that can cause rapidly progressive dementia.

What conditions can mimic dementia?

8 common diseases that mimic dementia

• Thyroid disease. The thyroid makes hormones that keep every system in the body running smoothly.
• Diabetes.
• Alcohol abuse.
• Vision or hearing problems.
• Heart or lung conditions.
• Liver or kidney disease.
• Tumors.
• Cancer.

What can cause sudden onset dementia?

What Causes RPD?

• Autoimmune diseases (conditions that over-activate the immune system)
• Unusual presentations of more common neurodegenerative diseases (such as Alzheimer’s disease)
• Prion diseases (rare forms of neurodegenerative disease)
• Infections.
• Impaired blood flow to or in the brain.
• Exposure to toxic substances.

What is mild cognitive disorder?

Mild cognitive impairment (MCI) is the stage between the expected cognitive decline of normal aging and the more serious decline of dementia. It’s characterized by problems with memory, language, thinking or judgment.

Is cognitive decline reversible in adolescence?

While there is a tendency to equate progressive neurological and/or cognitive decline with primary neurodegenerative diseases, it is vital to consider causes of reversible, “pseudo-” regression. Cognitive decline in adolescence is most likely to manifest as underachievement or failure at school.

What are the difficulties of children with Down syndrome?

Difficulties speaking clearly – Children with Down syndrome typically babble like other children. However, they do not move on to attempt to say words but tend to use more gestures for longer than other children with a similar level of understanding.

Cognitive decline is among the normal processes of aging. It happens at different times and is noticed to affect different elements of people’s lives, but it always has the same overall effect. Cognitive decline simply means that your brain doesn’t work as well as it used to.

What are the main causes of cognitive impairment in adolescence?

The main causes in the adolescent age group are Unverricht-Lundborg disease (where the cognitive involvement is modest and slowly progressive), Lafora body disease (rapid dementia), and myoclonic epilepsy with ragged red fibres (MERRF).
