Validation of Cognitive Screenings for the Hearing Impaired

November 5, 2020 updated by: University College, London

Validation of "Montreal Cognitive Assessment (MoCA) and Addenbrooke's Cognitive Examination III (ACE-III) "as a Cognitive Screening Tools for the Hearing Impaired

There are currently no cognitive tests that have been validated as screening tools for people with dementia and comorbid hearing loss. This is particularly important given the high prevalence of hearing impairment in older adults presenting to memory services and the risk of misdiagnosis of dementia in this population as outlined above.

Cognitive tests validated in hearing impaired populations will also be important as outcome tools for interventional research aiming to find out if treating hearing loss may reduce dementia risk in the longer term.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

Detailed Description

Hearing loss is very prevalent in older population. This leads to further problems such as communication problem, isolation from the community and depression. Moreover, hearing impairment may potentially affect the patients' cognitive function as demonstrated in the above mentioned published papers.

Communication problems that arise from a hearing loss alone can also interfere with administration of cognitive test battery, as a previous study showed that re-administered of MMSE test with assistive listening device can immediately improve the test score among elderly (1).

Therefore, special adaptation of the cognitive test battery to address the needs of hearing impaired older adult is necessary. This is to ensure that the test result reflects the exact cognitive state of the older adult with hearing impairment, not effected by hearing loss.

Moreover, appropriate cut-off point scores for hearing impaired population should be identified for these new cognitive screening tools. This is to ensure appropriate referral for further diagnosis and prompt management for cognitive impairment/dementia among older adults with hearing loss.

In addition, since hearing loss can potentially lead to deterioration in patients' cognitive function over time (2). Follow up assessments of cognitive function among older adults with hearing impairment can determine the rate of deterioration in retrospective trial(2). This prospective trial follow up of cognitive function among hearing loss participants may uncover additional risk factors associated with the deterioration. Better understanding of these risk factors can potentially lead to further intervention in order to delay decline in patients' cognitive function.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

61 years and older (Older Adult)

Description

Inclusion Criteria:

  • Age over 65 years
  • Documented Hearing loss (currently wearing hearing aids and/or hearing testing with a hearing average of >/= 30dB HL in D-HI,MCI-HI group)

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure
Measure Description
Time Frame
The adapted version Montreal Cognitive Assessment (MoCA) questionnaire total score among dementia/mild cognitive impairment/normal cognition group of hearing impaired older adult.
Time Frame: approximately 1 years (expected to recruit 30 participants for each group)
The score will be used to calculate the appropriate cut-point score for differentiating each group of hearing impaired older adults.(total score ranging from 0-30 points with higher score indicate better cognitive function)
approximately 1 years (expected to recruit 30 participants for each group)
The adapted version Addenbrooke's Cognitive Examination III (ACE-III) questionnaire total score among dementia/mild cognitive impairment/normal cognition group of hearing impaired older adult.
Time Frame: approximately 1 years (expected to recruit 30 participants for each group)
The score will be used to calculate the appropriate cut-point score for differentiating each group of hearing impaired older adults (total score ranging from 0-100 points with higher score indicate better cognitive function)
approximately 1 years (expected to recruit 30 participants for each group)

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Hearing handicap score from the Modified Amsterdam Inventory for Auditory Disability and Handicap (mAIAD) (total score ranging from 0-84 with higher score indicate smaller perceived hearing difficulty)
Time Frame: approximately 1 years (expected to recruit 30 participants for each group)
The score from mAIAD and the hearing threshold from audiogram (in dB HL) along with the MoCA and ACE-III test scores will be used to determine what best predicts hearing handicap in the cognitively impaired population.
approximately 1 years (expected to recruit 30 participants for each group)

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants. For observational studies, a measurement or observation that is used to describe patterns of diseases or traits, or associations with exposures, risk factors, or treatment. Types of outcome measures include primary outcome measure and secondary outcome measure.
Outcome Measure
Measure Description
Time Frame
Final cognitive status diagnosis (base on ICD-10 coding system; dichotomous outcome; code F00-F03 (dementia) or code ICD F06.7 (Mild cognitive impairment)) provided by an NHS memory service doctors at routine clinical care follow up session at 1 year.
Time Frame: 1 year follow up from initial recruitment
The final cognitive status diagnosis of the population will be compared with hearing and cognitive outcome measures at baseline ie. the hearing threshold from audiogram (in dB HL)) and MoCA and ACE-III tests score and mAIAD questionnaire scores to determine what parameters best predict cognitive change in diagnosis from the baseline assessments in hearing impaired/cognitive impaired population.
1 year follow up from initial recruitment
