Association of Anticholinergic Burden With Onset of Delirium in Older Adults With Alzheimer Dementia:
An observational study of Delirium and Anticholinergic Adverse Reaction, run by Gulhane Training and Research Hospital at 1 site in Turkey (Türkiye).
Trial summary
Drugs with anticholinergic properties are commonly prescribed to older persons despite growing evidence of their significant adverse effects. However, limited data are available concerning their contribution to time of onset of delirium. Read more about this study

About this study
Official title: Association of Anticholinergic Burden With Onset of Delirium in Older Adults With Alzheimer Dementia: A Retrospective Cohort Study
Drugs with anticholinergic properties are commonly prescribed to older persons despite growing evidence of their significant adverse effects. However, limited data are available concerning their contribution to time of onset of delirium. This study aimed to determine the potential association of higher anticholinergic burden to early-onset of delirium superimposed dementia in the older adult.
- Being tested
- Anticholinergic burden
- Medical subject headings
- Delirium, Alzheimer Disease
What participants receive
What participants receive. In a randomised study each person is assigned to one group by chance.
Anticholinergic burdenDrug
The anticholinergic burden (ACB) was assessed using the Anticholinergic Burden Scale.
Higher ACB was described as equal or higher than 1.
| Study group | Role | What they receive |
|---|---|---|
| early onset deliryum on dementia | It was earlier than The median time of onset of delirium superimposed dementia Receives: Drug: Anticholinergic burden | |
| Delirium on dementia (normal) | It was equal or later than The median time of onset of delirium superimposed dementia Receives: Drug: Anticholinergic burden |
What is being measured
The primary outcome is the main question the study is designed to answer.
Time onset of delirium superimposed dementia
First attack of delirium onset
Measured: 12 month

Questions about this trial
What is this clinical trial studying?
An observational study of Delirium and Anticholinergic Adverse Reaction, run by Gulhane Training and Research Hospital at 1 site in Turkey (Türkiye).
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 1 inclusion and 1 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 24 Sep 2021. 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?

How can a doctor refer a patient or contact the research team?
Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Time onset of delirium superimposed dementia (time frame: 12 month). 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 24 Sep 2021; AzTrials last refreshed its copy on 8 Nov 2026.
