MCI means memory or thinking problems are greater than expected for age, while normal activities are still mostly possible.^[1,2]

People may lose things often, forget events or appointments, or have more trouble finding words than peers.^[1]
MCI can be an early sign of Alzheimer disease, but it is not the same word as dementia.^[1,2]
Daily independence is a central part of the boundary.^[1,3]

MCI is a clinical category, not just the feeling of being forgetful.^[1]

Cognitive testing can assess memory, thinking, and language patterns.^[4,1]

Normal activities remaining mostly possible separates MCI from dementia-level daily-life impairment.^[1,3]

MCI may reflect early neurodegenerative disease, vascular disease, medicines, depression, sleep problems, sensory loss, or other causes.^[1,2,5]
MedlinePlus notes that memory problems can also have causes such as medicines and vascular diseases, and some problems from these conditions can be managed.^[1]
The key question is not only memory score, but whether function is changing over time.^[1,4]

Clinicians may use thinking, memory, and language tests, specialist assessment, and follow-up over time.^[1,4]
MedlinePlus states there is no proven drug treatment for MCI at this time.^[1]
Clinical review may look for modifiable contributors such as medicine effects, sleep, depression, sensory loss, and vascular risks.^[5,1]
