Can you tell the difference between age-related memory decline versus dementia?memory clinic

Yes, a short neuropsychological screener at Harbor Mental Health’s memory clinic can help make this distinction.

As we age, our brain changes: some of these changes are expected or age-related while other changes reflect a more significant decline that may indicate a type of dementia. A neuropsychological screener is a quick method of distinguishing between normal / expected age-related decline and dementia (including the type of dementia). The individual’s functioning capacity in different neurocognitive domains (intelligence, attention, processing speed, motor skills, spatial capacity, memory, and language) can also be assessed.

Dementia can be described as a significant decline from the previous level of neurocognitive functioning capacity (irrespective of type) as described in the DSM-5. Types of dementia include Alzheimer’s disease, Frontotemporal lobar degeneration, Lewy body disease, Vascular disease, Traumatic Brain Injury (TBI) and neurocognitive decline, HIV infection and neurocognitive decline, Prion disease, Parkinson’s disease, Huntington’s disease, substance/medication related dementia, another medical condition leading to dementia, and unspecified dementia). Dementia influences everyday functioning, and social functioning, and the cause of the symptoms marked distress in the patient. The DSM-5 allows for diagnostic categories ranging from mild to major symptoms, depending on the functioning capacity of the individuals.

When assessing the individual’s neurocognitive functioning, the following distinctions between age-related decline and dementia on neurocognitive domains include:

Intelligence

Age-Related Decline: Capacity for crystallized intelligence remains constant (ability to use previously learned knowledge), while capacity for fluid intelligence declines (problem-solving, using logic, and reasoning). Capacity for traditional reasoning tends to remain constant, while problem-solving capacity for new information becomes challenging.

Dementia: Presence of anosognosia (lack of insight), there is a general decline in reasoning and problem-solving abilities that influence the individual’s functioning capacity.

Attention

Age-Related Decline: The capacity for simple or focused attention (for instance, watching television) remains constant, while the capacity for divided attention and multitasking (for instance, watching television and talking on the phone) is compromised.

Dementia: There is a general decline in an attentional capacity that influences encoding, storage, and retrieval. There is also a decline in the capacity to attend to information to cohesively process it. For instance, the inability to attend to reading, conversations, television, movies etc.

Processing Speed

Age-Related Decline: There is a decline in the mental processing speed of information.

Dementia: The decline in the speed of processing mental information interferes with the capacity for daily functioning and carrying out everyday tasks.

Motor Skills

Age-Related Decline: There is a decline in motor speed capacity.

Dementia: The decline in motor skills interferes with daily activities such as driving, utilizing tools, etc.

Spatial Capacity

Age-Related Decline: There is a decline in the ability to perceive objects in space or there is a decline in spatial memory.

Dementia: The decline in spatial capacity influences everyday functioning. For example, the individual may have difficulty with finding new places or drawing a map for someone.

Memory

Age-Related Decline: Capacity to retain memories of remote and past events is preserved, while capacity for recent past or forming new memories declines.

Dementia: Presence of amnesia, memory deficits that influence daily functioning ability because the patient forgets daily scheduled activities, keeping up with medication regimen, remembering instructions, keeping up with schedules: i.e. social events, paying bills, making appointments.

Language

Age-Related Decline: Vocabulary capacity remains constant while capacity for word-finding (recalling words to complete conversations) and capacity for name finding (recalling names of people and objects) declines.

Dementia: Presence of aphasia, speech impairment that could be receptive and/or expressive based on the type of dementia. For instance, the patient may have difficulty following directions, understanding, and responding to conversations, difficulty with reading and written language, etc.
