Cognitive Tests for Dementia Diagnosis

Mini Cog

A person can complete this quick screening exam in three minutes. Two tests are given by a doctor: a clock drawing test and a three-word registration and memory test.

A clock face with all the digits and the time the doctor prescribes must be drawn.

When someone hears three words from a doctor and repeats them, this is known as three-word registration and recall. They will need to know and recollect these terms one more time after the clock-drawing test.

The test carries a maximum possible score of 5 points. Although those with a score of 3-5 are less likely to develop dementia, it does not rule out the possibility of mild cognitive impairment.

The Montreal Cognitive Assessment (MoCA)

The Montreal Cognitive Assessment (MoCA) is a test that aids medical practitioners in identifying Alzheimer’s disease and moderate cognitive impairment in patients.

It is a more accurate gauge of cognitive performance than the MMSE, according to a 2021 study.

It has 30 questions and takes between 10 and 12 minutes to complete. Doctors do not consider someone to have a cognitive impairment if they receive a score of 26 or higher.

People with mild cognitive impairment had an average score of 22.1 in the first study data, whereas those with Alzheimer’s disease had an average score of 16.2.

The test is helpful in determining cognitive loss in disorders other than dementia, such as

  • Huntington’s disease [3]
  • Parkinson’s disease [4]
  • amyotrophic lateral sclerosis (ALS) [5]
  • stroke [6]
  • multiple sclerosis [7]
  • brain metastasis
  • schizophrenia [8]
  • depression [9]

This tool is utilized by different healthcare professionals including family doctors, neurologists, geriatric psychiatrists, occupational therapists and speech-language therapists.
