Understanding Neurocognitive Functioning
The Brain’s Role in Overall Health and Well-being
The brain is not only responsible for cognitive functions like decision-making and communication. It controls your emotions, motor skills, vision, respiration, and every other part of the body.
The brain connects to the spinal cord, a vital portion of the central nervous system, allowing access to all nerves in the body. If your brain isn’t functioning correctly, this directly affects other vital functions and can cause health conditions to develop, lowering your quality of life.
Key Components of Neurocognitive Function
The brain has six key functions as outlined by the DSM-5:
- Complex attention. The ability to focus on multiple tasks at once and make intentional decisions on what to pay attention to and what to ignore.
- Executive function. High-level cognitive skills include planning, prioritizing, decision-making, and task management.
- Learning and memory. The ability to record information and draw from it when needed.
- Language. Skills related to communicating orally, in writing, and reading. Language abilities aid in object naming, word selection, speech fluency, grammar, syntax, and receptive language.
- Perceptual-motor control. Coordination skills that allow you to respond to stimuli and interact with your environment, including your choice of response and reaction time.
- Social cognition. The ability to process, record, and draw information from social contexts to explain and predict your and others’ behaviors.
The Difference Between Normal Cognitive Aging and Cognitive Decline
Aging is a natural process that each person goes through. As you grow older, your brain goes through a process of developing and eventually declining. Cognitive decline typically occurs around age 70 and older. This process may be more rapid in the case of abnormal cognitive decline.
Abnormal cognitive decline causes more severe changes to thinking abilities. It’s characterized by becoming more forgetful, losing your train of thought, and having trouble following a conversation, among other things. This condition may occur due to dementia, stroke, traumatic brain injury, and developmental disabilities.
What the Neurocognitive Index Measures
Key Biomarkers and Indicators of Brain Health
We’ve outlined critical indicators of your brain’s health. High levels of or deficiencies in specific biomarkers can put you at higher risk of conditions such as cardiovascular disease and dementia.
Omega 3
The Omega 3 Index measures your bloodstream’s DHA (docosahexaenoic acid) and EPA (eicosapentaenoic acid) levels. Higher amounts of these acids are associated with better brain health. Where your levels are at tends to depend on dietary and genetic factors.
Vitamin B12
Vitamin B12 is an essential nutrient in your body. It contributes to the production of necessary chemicals like dopamine, norepinephrine, and serotonin, which produce energy and keep you sharp and happy.
Vitamin D
Adequate amounts of vitamin D support your bones, muscles, immune system, and brain health. Deficiencies in this essential vitamin are associated with cognitive impairment, poor immune function, and nervous system disorders.
Red Blood Cell (RBC) Magnesium
Magnesium contributes to healthy muscles, nerves, bones, and blood sugar levels. Not enough magnesium in your daily caloric intake can increase your risk of brain-related health problems, including stroke and osteoporosis.
ApoB:ApoA
The ApoB:ApoA ratio biomarker looks at the balance of inflammation in cholesterol particles. Balanced levels are associated with a healthier heart and brain, while unbalanced levels can increase your risk for heart disease and related conditions.
Homocysteine
The amino acid homocysteine is broken down by vitamins B12, B6, and folate to produce essential chemicals in the body. When homocysteine levels become elevated, your risk of cardiovascular disease, brain atrophy, white matter hyperintensity, and other harmful brain conditions can increase.
Phospholipid DHA
DHA is an omega-3 fatty acid located in the brain and nerves. It contributes to cognitive performance, memory, and reasoning abilities. Low levels of DHA are associated with poor neurological development, low IQ, cognitive dysfunction, and a greater risk for Alzheimer’s disease.

The Implications of Altered Neurocognitive Function
Common Neurocognitive Disorders and Their Symptoms
Neurocognitive disorders can be divided into three categories: Delirium, mild neurocognitive disorder, and major neurocognitive disorder.
Delirium causes rapid changes to the brain’s physical matter. The impact is sudden and powerful, causing mental confusion and changes in emotions, perception, movement, and consciousness. You may experience disruptions in sleep patterns, a decline in short-term memory, and disorganized thinking. Blood and urine tests can assist in gaining a diagnosis and treatment to alleviate these symptoms.
Mild neurocognitive disorder is characterized by a decreased mental function that lessens the quality of life but still allows you to be independent in your daily living. Some examples of symptoms accompanied by this disorder include forgetfulness and difficulty with recalling, retaining, or learning new information.
Major neurocognitive disorder creates a much greater strain on a person’s life, making independent living extremely difficult to impossible. A diagnosis requires a significant decline in at least one of the main cognitive domains: executive function, complex attention, language, learning, memory, perceptual-motor, or social cognition.
Types of Neurocognitive Disorders | Most Common Symptoms |
---|---|
Alzheimer’s Disease | – Memory loss – Confusion – Loss of balance/coordination – Aggression/irritability – Wandering – Personality changes – Depression – Hallucinations – Paranoia |
Creutzfeldt-Jakob Disease | – Memory loss – Loss of balance/coordination – Slurred speech – Vision problems/blindness – Jerking muscle spasms – Rhythmic muscle contractions – Amnesia or dementia – Delusion – Lack of concentration – Anxiety, depression, or apathy |
Frontotemporal Degeneration | – Personality changes – Inappropriate, impulsive, or repetitive behaviors – Impaired judgment – Apathy/lack of empathy – Decreased self-awareness – Loss of energy and motivation – Emotional withdrawal – Agitation -Difficulty planning and organizing |
Huntington’s Disease | – Difficulty concentrating – Memory lapses – Depression – Stumbling and clumsiness – Mood swings – Involuntary jerking or fidgety movements of the limbs and body – Difficulty speaking clearly – Swallowing problems – Slow or rigid movements – Personality changes – Breathing problems |
Lewy Body Disease | – Decline in cognitive abilities – Visual hallucinations – Sleep problems – Concentration problems – Apathy and loss of motivation – Depression – Slowed movement – Tremored/shuffled walk – Rigid muscles – Loss of bladder control |
Parkinson’s Disease | – Body tremors – Muscle stiffness – Slowness of movement – Impaired balance/coordination – Depression – Difficulty swallowing, chewing, and speaking – Urinary problems or constipation – Skin problems – Memory problems -Inability to plan and accomplish tasks |

The Impact of Chronic Illnesses on Brain Function
Chronic illness is commonly associated with a decline in cognitive functioning due to its effect on essential processes. For example, diabetes, hyperlipidemia, and hypertension are related to vascular dementia through disrupting circulation to the brain. Likewise, chronic illnesses can throw off vital brain chemicals, including GABA, serotonin, dopamine, and norepinephrine, which contribute to good cognitive and emotional health.
Lifestyle Factors That Influence Neurocognitive Health
Research has found several behaviors and habits linked to your neurological well-being.
- Physical Activity. One 2020 study found that regular exercise can improve brain function by up to 15%.
- Balanced Diet. Researchers found a 53% lower rate of Alzheimer’s disease for those with the highest MIND diet scores, a diet that focuses on brain-healthy foods.
- Smoking. A 2015 study discovered that people who smoke are 30% more likely to develop dementia than people who do not.
- Alcohol. Alcohol is a neurotoxin that can disrupt brain communications and affect brain cells’ functions.
