It usually affects cognitive, physical, emotional, social or independent functioning. ABIs can result from either a traumatic brain injury or a non-traumatic injury such as stroke, infection or substance abuse.
A neurocognitive deficit is a reduction or impairment of cognitive function in one of these areas, but particularly when physical changes can be seen to have occurred in the brain, such as aging related physiological changes or after neurological illness, mental illness, drug use, or brain injury.

For example, the Copenhagen consensus, states that lack of both iodine and iron has been implicated in impaired brain development, and this can affect enormous numbers of people: it is estimated that 2 billion people (one-third of the total global population) are affected by iodine deficiency, including 285 million 6- to 12-year-old children.
Focal neurologic signs, also known as focal neurological deficits or focal CNS signs, are impairments of nerve, spinal cord, or brain function that affects a specific region of the body, e.g. weakness in the left arm, the right leg, paresis, or plegia.
Brain injuries have far-reaching and varied consequences due to the nature of the brain as the main source of bodily control. Brain-injured people commonly experience issues with memory. [15] This can be issues with either long or short-term memories depending on the location and severity of the injury.
Lower brain oxygen levels caused by sleep apnea were linked to changes to the white matter, which could lead to cognitive problem, a new study suggests. Sleep apnea impacts brain in ways that may ...

[1] Cognition, also known as cognitive function, refers to the mental processes of how a person gains knowledge, uses existing knowledge, and understands things that are happening around them using their thoughts and senses.

What's more, this immediate brain health benefit was observed regardless of whether the activities were high intensity (think running or jogging) or lower intensity (like walking or household chores).
