Dementia is a common term for conditions such as Alzheimer’s and other neurocognitive disorders. These disorders affect the nerve cells and often impact a person’s ability to remenber, to reason, and to make judgments. They usually develops as people age, but they can affect younger people too.
Major neurocognitive disorder, known previously as dementia, is a decline in mental ability severe enough to interfere with independence and daily life.
Major or mild neurocognitive disorder (NCD) due to Alzheimer disease is a neurodegenerative disease with an insidious onset and gradual progression of cognitive, behavioral, and functional impairment beyond what might be expected from normal aging [1].
It should be noted that the primary difference between major and mild neurocognitive disorder is the severity of the decline and independent functioning.
The key distinction between major and mild neurocognitive disorder is that individuals with major neurocognitive disorder experience a substantial decline in function that includes a loss of independence as a result of profound cognitive impairment, whereas individuals with mild neurocognitive disorder experience only …
Major Neurocognitive Disorder (MND) – previously called dementia – is a syndrome that progresses with significant deterioration of cognitive domains as compared to previous levels of cognitive performance in memory, speech, reasoning, intellectual function, and/or spatiotemporal perception, and may also be associated …
MCI refers to relatively minor impairments in thought processes and memory, whereas Alzheimer’s is a specific disease in which memory and functioning continue to significantly decline over time.
Dementia is a decline in cognitive function. To be considered dementia, mental impairment must affect at least two brain functions. Dementia may affect: memory.
MCI isn’t considered dementia, but roughly 10 to 15 percent of people with MCI may develop dementia each year, including a specific type of dementia known as Alzheimer’s disease.
The most common major NCDs are AD, vascular dementia (VaD), dementia with Lewy body (DLB), and frontotemporal lobar degeneration. There can be overlap in all of these dementias.
Major neurocognitive disorder (MNCD) with behavioral disturbance, also known as behavioral and psychological symptoms of dementia (BPSD), consists of behaviors and psychiatric symptomatology which are not readily assessed by standard neuropsychological testing batteries, nor do the symptoms always present as …
Delirium is typically caused by acute illness or drug toxicity (sometimes life threatening) and is often reversible. Dementia is typically caused by anatomic changes in the brain, has slower onset, and is generally irreversible.
Major and mild neurocognitive disorders can occur with Alzheimer’s disease, degeneration of the brain’s frontotemporal lobe, Lewy body disease, vascular disease, traumatic brain injury, HIV infection, prion diseases, Parkinson’s disease, Huntington’s disease, or another medical condition, or they can be caused by a …
The key distinction between major and mild NCD is that persons with major NCD experience a substantial decline in function (loss of independence) as a result of profound cognitive impairment, whereas subjects with mild NCD experience only a modest cognitive decline and, as a result, function relatively independently.
Dementia was replaced in DSM-5 because the term was deemed stigmatizing; the rough translation from the Latin roots is “loss of mind.” Acknowledging that old habits die hard, however, DSM-5 also states that use of the term is not precluded “where that term is standard.”
Delirium is typically caused by acute illness or drug toxicity (sometimes life threatening) and is often reversible. Dementia is typically caused by anatomic changes in the brain, has slower onset, and is generally irreversible.

Major vascular neurocognitive disorder (NCD) is the second leading form of dementia after Alzheimer’s disease, accounting for 17-20% of all dementias. Vascular. NCD is a progressive disease caused by reduced cerebral blood flow related to multiple large volume or lacunar infarcts that induce a sudden onset and stepwise.
Lewy body dementia (LBD) is a disease associated with abnormal deposits of a protein called alpha-synuclein in the brain. These deposits, called Lewy bodies, affect chemicals in the brain whose changes, in turn, can lead to problems with thinking, movement, behavior, and mood.
Does Mild Cognitive Impairment Lead to Dementia? Researchers have found that more people with MCI than those without it go on to develop Alzheimer’s disease or a related dementia. An estimated 10 to 20% of people age 65 or older with MCI develop dementia over a one-year period.
Dementia is the loss of cognitive functioning — thinking, remembering, and reasoning — to such an extent that it interferes with a person’s daily life and activities. Some people with dementia cannot control their emotions, and their personalities may change.
Neurocognitive disorders aren’t caused by a mental disorder. However, many of the symptoms of neurocognitive disorders are similar to those of certain mental disorders, including schizophrenia, depression, and psychosis.
DSM-5: Neurocognitive Disorder Dementia is the umbrella term for a number of neurological conditions, of which the major symptom is the decline in brain function due to physical changes in the brain. It is distinct from mental illness. New diagnostic criteria for dementia were developed and released in 2013.
What Is Cognitive Impairment? Cognitive impairment is when a person has trouble remembering, learning new things, concentrating, or making decisions that affect their everyday life.
Behavioral disturbances in dementia are often globally described as “agitation” including verbal and physical aggression, wandering, and hoarding. These symptoms create patient and caregiver distress, and lead to nursing home placement.
Neurocognitive disorder due to TBI is diagnosed when persistent cognitive impairment is observed immediately following the head injury, along with one or more of the following symptoms: loss of consciousness, posttraumatic amnesia, disorientation and confusion, or neurological impairment (APA, 2013).
Home healthcare clinicians need to understand symptoms of each of these conditions and remain astute in their assessment of these distinctly different entities. Failure to correctly identify delirium, dementia, and/or depression can delay treatment and result in poor quality of life.
Delirium often occurs in the context of a pre- existing neurocognitive disorder, as the impaired brain functionality of an individual with mild and major neurocognitive disorder (also known as dementia) may make them more susceptible to delirium.
