Brain damage and cognitive decline

  • How does brain damage cause memory loss?

    Any disease or injury that affects the brain can affect memory.
    Amnesia can result from damage to brain structures that form the limbic system, which controls emotions and memories.
    They include the thalamus found deep within the center of the brain..

  • Most studies suggest that once brain cells are destroyed or damaged, for the most part, they do not regenerate.
    However, recovery after brain injury can take place, especially in younger people, as, in some cases, other areas of the brain make up for the injured tissue.
Traumatic brain injuries are associated with cognitive decline later in life, and a sharper drop in cognition as we age, a study of twins 
Traumatic brain injuries are associated with cognitive decline later in life, and a sharper drop in cognition as we age, a study of twins who served in World War II shows.
Traumatic brain injury (TBI) results from an impact to the head that disrupts normal brain function. TBI may affect a person's cognitive abilities, including learning and thinking skills.

Overview

Mild cognitive impairment (MCI) is the stage between the expected decline in memory and thinking that happens with age and the more serious decline of dementia.
MCImay include problems with memory, language or judgment.
People with MCImay be aware that their memory or mental function has "slipped." Family and close friends also may notice changes. .

Risk Factors

The strongest risk factors for MCIare:.
1) Increasing age.
2) Having a form of a gene known as APOE e4.
This gene also is linked to Alzheimer's disease.
But having the gene doesn't guarantee that you'll have a decline in thinking and memory.
Other medical conditions and lifestyle factors have been linked to an increased risk of changes in thinking, .
