After a TBI, a person's ability to process and understand information often slows down and can become more challenging. This can result in some of the following problems: Having trouble understanding what others are saying or needing more time to understand what others are saying..
What are the 4 types of cognitive impairment?
Cognitive Disorders Attention deficit disorder. Dementia with Lewy bodies disease. Early onset dementia. Epilepsy-related cognitive dysfunction..
What causes cognitive dysfunction?
While age is the primary risk factor for cognitive impairment, other risk factors include family history, education level, brain injury, exposure to pesticides or toxins, physical inactivity, and chronic conditions such as Parkinson's disease, heart disease and stroke, and diabetes..
What part of the brain is affected by cognitive impairment?
The damaged areas of the brain include the hippocampus, which is an area of the brain that helps new memories form. Damage to the frontal lobe of the brain eventually causes problems with intelligence, judgment, and behaviour. Damage to the temporal lobe affects memory. And damage to the parietal lobe affects language..
The brain controls many aspects of thinking — remembering, planning and organizing, making decisions, and much more. These cognitive abilities affect how well we do everyday tasks and whether we can live independently. Some changes in thinking are common as people get older.

Cognitive disorders are defined as any disorder that significantly impairs the cognitive functions of an individual to the point where normal
Major neurocognitive disorder(previously known as dementia) is characterized by significant cognitive decline and the development of dependence.EtiologyHistory and PhysicalEvaluationPrognosis
Cognitive impairment can result from direct and indirect trauma to the brain, hypoxia, edema, metabolic disturbances, neurodegenerative processes, metabolic encephalopathies, electrolyte abnormalities, organ failure, pesticides, toxins, medications, and infective processes.
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. MCI may include problems with memory, language or judgment. People with MCI may be aware that their memory or mental function has "slipped."
How do you understand cognitive dysfunction?
Understanding cognitive dysfunction requires some background in cognitive function – knowing how the pieces fit together helps explain what happens when one or more of those pieces stops working well. When neuroscientists talk about cognitive functioning, we are referring to six main categories:.
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. .
What are functional brain disorders?
Functional brain disorders with detectable destruction of brain connections or networks, such as:
neurodegenerative diseases (eg
Parkinson’s disease
Alzheimer’s disease
and other dementias) and mental disorders (eg
schizophrenia
depression
bipolar disorder
alcoholism
and drug abuse) .
What causes cognitive dysfunction after a neurological event?
And since most neurological pathologies – including:
stroke
injury
tumor
or event treatments – can lead to disruptions in one or more of these categories
it is common to see some degree of cognitive dysfunction after any neurological event.
Brain and cognitive dysfunction
Nerve tract from the cingulate gyrus to the entorhinal cortex in the brain
In neuroanatomy, the cingulum is a nerve tract – a collection of axons – projecting from the cingulate gyrus to the entorhinal cortex in the brain, allowing for communication between components of the limbic system. It forms the white matter core of the cingulate gyrus, following it from the subcallosal gyrus of the frontal lobe beneath the rostrum of corpus callosum to the parahippocampal gyrus and uncus of the temporal lobe.
Multidisciplinary field
Cognitive neuropsychiatry is a growing multidisciplinary field arising out of cognitive psychology and neuropsychiatry that aims to understand mental illness and psychopathology in terms of models of normal psychological function. A concern with the neural substrates of impaired cognitive mechanisms links cognitive neuropsychiatry to the basic neuroscience. Alternatively, CNP provides a way of uncovering normal psychological processes by studying the effects of their change or impairment.
Difficulty keeping organised to complete tasks
In psychology and neuroscience, executive dysfunction, or executive function deficit, is a disruption to the efficacy of the executive functions, which is a group of cognitive processes that regulate, control, and manage other cognitive processes. Executive dysfunction can refer to both neurocognitive deficits and behavioural symptoms. It is implicated in numerous psychopathologies and mental disorders, as well as short-term and long-term changes in non-clinical executive control.

Biochemical signaling between the gastrointestinal tract and the central nervous system
The gut–brain axis is the two-way biochemical signaling that takes place between the gastrointestinal tract and the central nervous system (CNS). The microbiota–gut–brain axis includes the role of gut microbiota in the biochemical signaling events that take place between the GI tract and the CNS. Broadly defined, the gut–brain axis includes the central nervous system, neuroendocrine system, neuroimmune systems, the hypothalamic–pituitary–adrenal axis, sympathetic and parasympathetic arms of the autonomic nervous system, the enteric nervous system, vagus nerve, and the gut microbiota.
Postoperative cognitive dysfunction (POCD) is a decline in cognitive function that may last from 1–12 months after surgery, or longer. In some cases, this disorder may persist for several years after major surgery. POCD is distinct from emergence delirium. Its causes are under investigation and occurs commonly in older patients and those with pre-existing cognitive impairment.
