About this study

Official title: PET-CT-based Study of Central Mechanisms of Cortical Metabolism in 18F-FDG and 18F-AV1451 Age-related Deafness: a Cross-sectional Study

The participants were recruited from elderly subjects in the age range of 60-85 years and audiological assessments, cognitive function assessments, non-invasive brain imaging, behavioral assessments were collected from the normal control group, the elderly deaf non-hearing group and the elderly deaf hearing group according to the inclusion and exclusion criteria. The project aims to investigate the differences in auditory speech and cognitive function in age-related deafness at the behavioural level, and to investigate the central cortical metabolic mechanisms in age-related deafness at the brain imaging level.

Read the detailed description

The participants were recruited from elderly subjects in the age range of 60-85 years and audiological assessments (pure tone audiometry, speech audiometry), cognitive function assessments (Simple Mental State Examination MMSE scale, Montreal Cognitive Assessment Scale MoCA scale), non-invasive brain imaging (functional near-infrared spectroscopy fNIRS, EEG/ERP), behavioral assessments (functional near-infrared spectroscopy fNIRS, EEG/ERP, PET/CT, etc.) were collected from the normal control group, the elderly deaf non-hearing group and the elderly deaf hearing group according to the inclusion and exclusion criteria. The project aims to investigate the differences in auditory speech and cognitive function in age-related deafness at the behavioural level, and to investigate the central cortical metabolic mechanisms in age-related deafness at the brain imaging level.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. pure tone average

    The pure tone hearing threshold of each octave was tested under standard test conditions. Pure tone average(PTA, an average air conductance threshold of 500, 1000, 2000 and 4000Hz) and high frequence pure tone average(HF-PTA, an average air conductance threshold of 2000, 4000 and 8000Hz) were calculated for analysis

    Measured: through study completion, an average of 6 months

  2. Speech recognition score

    Speech recognition score was tested under standard test conditions.The stimulus material is a two-syllable word list of Mandarin speech audiometry materials.

    Measured: through study completion, an average of 6 months

  3. MMSE score and grade

    The scale is divided into seven aspects, including time orientation, place orientation, immediate memory, attention and gauging, delayed memory, language and visual space. There are 30 items in the scale, with a total score of 30. Normal 27 to 30, mild cognitive impairment 21 to 26, moderate cognitive impairment 10 to 20, and severe cognitive impairment 0 to 9.

    Measured: through study completion, an average of 6 months

  4. MoCA score and grade

    Montreal Cognitive Assessment (Montreal Cognitive Assessment) is a rapid screening tool for abnormal cognitive function. The scoring criteria were: 26 to 30 points for normal cognitive impairment, 18 to 25 points for mild cognitive impairment, 10 to 17 points for moderate cognitive impairment, and 0 to 9 points for severe cognitive impairment.

    Measured: through study completion, an average of 6 months

  5. Otorhinolaryngological diseases and daily life self-assessment questionnaire

    The questionnaire included otitis media, tinnitus, deafness, ear pain, ear tightness, ear leakage, ear itching, course of disease, severity of self-complaint, etc

    Measured: through study completion, an average of 6 months

  6. Resting Electroencephalogram

    Electroencephalogram (EEG) is applied to collect the spontaneous and rhythmic biologic potential data of the subjects' resting brain, namely, 8-minute resting state data with their eyes closed without any visual or auditory stimulation, in a dark environment.

    Measured: through study completion, an average of 6 months

  7. Functional Near-Infrared Spectoscopy

    Functional near-infrared Spectoscopy(fNIRS) is used to collect the changes of oxygenated hemoglobin and deoxygenated hemoglobin in the temporal lobe of a subject during brain activity by using a portable Near Infrared optical signal analysis system from Shimadsu, Japan.

    Measured: through study completion, an average of 6 months

  8. Positron emmision tomography

    Pet-ct, Positron emmision tomography is adopted by Siemens PET/CT integrated machine in Germany.

    Measured: through study completion, an average of 6 months

Questions about this trial

What is this clinical trial studying?

An observational study of Age-related Hearing Loss and PET-CT, run by Sun Yat-Sen Memorial Hospital of Sun Yat-Sen University at 1 site in China.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 4 inclusion and 3 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 3 Apr 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

Contact Minqian Gao, B.Sc (13660778861, gaomq6@mail.sysu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

pure tone average (time frame: through study completion, an average of 6 months). The study lists 8 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 3 Apr 2023.
