What is being measured
The primary outcome is the main question the study is designed to answer.
Test of Masticating and Swallowing Solids
Test of Masticating and Swallowing Solids (TOMASS) is a standardized clinical assessment used to evaluate solid bolus mastication and swallowing performance.
Measured: Baseline (single-task and dual-task conditions assessed on the same day)
Mini-Mental State Examination (MMSE)
The MMSE is a brief, widely used screening tool for assessing global cognitive function.
Measured: Baseline
Go/No-Go Test
The Go/No-Go Test is a neuropsychological assessment used to evaluate response inhibition and sustained attention.
Measured: Baseline (single-task and dual-task conditions assessed on the same day)
Auditory Reaction Time Test
The Auditory Reaction Time Test is used to assess auditory attention and the speed of motor response to auditory stimuli.
Measured: Baseline (single-task and dual-task conditions assessed on the same day)
Tap Tool
The Tap Tool is a neuropsychological and motor performance assessment used to evaluate psychomotor speed and fine motor control.
Measured: Baseline (single-task and dual-task conditions assessed on the same day)

The record says: opening soon, as of the sponsor's last update on 26 Jan 2026. 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 Turkey (Türkiye). 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?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Seda Nur Kemer, PhD (+905467861866, sedakemer@gmail.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Test of Masticating and Swallowing Solids (time frame: Baseline (single-task and dual-task conditions assessed on the same day)). The study lists 5 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 26 Jan 2026.
