About this trial
This study aims to evaluate how effective trazodone is in treating insomnia in adults aged 65 years and older. The main question it aims to answer is :
\- Is trazodone more effective than a placebo in reducing the severity of insomnia symptoms in older adults?
Participants will :
* Take 25 to 50 mg of trazodone or a matching placebo before bed for 28 days. After a 2-week break, they will then take the other medication for another 28 days. * Visit the clinic three times for checkup and test * Complete a sleep diary and wear an actimeter during the night.

Primary outcomes
Insomnia severity index
The ISI is a self-assessment questionnaire that evaluates the nature, severity, and impact of insomnia. The typical recall period is the past month. The dimensions assessed are: the severity of falling asleep, maintaining sleep, and waking up too early in the morning; sleep dissatisfaction; the interference of sleep difficulties with daytime functioning; the visibility of sleep problems to others; and the distress caused by sleep difficulties. A 5-point Likert scale is used to evaluate each item. The total score is interpreted as follows: no insomnia 0-7; subclinical insomnia 8-14; moderate insomnia 15-21; and severe insomnia 22-28. It is increasingly used as a measure of treatment response in clinical research. Data confirm its reliability and the validity of the measurements obtained in the older adult population.
Secondary outcomes
Insomnia daytime symptoms and Impacts Questionnaire
The IDSIQ is a questionnaire covering 14 different items that specifically measures the impact of insomnia on various aspects of daytime functioning. The questions are grouped into three areas, each representing the main daytime symptoms and impacts of insomnia on drowsiness (four items), alertness/cognition (six items), and mood (four items). Each item is rated on an 11-point numerical scale (from 0 to 10), with lower scores indicating better daytime functioning. It has been found to be sensitive to changes in patients experiencing daytime effects. It is quick to administer, easy to complete, and has reliable reproducibility (test-retest). It can be used in clinical trials to assess changes and the effectiveness of a treatment on daytime functioning and for the recording of new drugs for insomnia. Regulatory authorities now require that the effectiveness of clinical trials for medical products against insomnia be measured not only by treating physicians but also by the p
Subjective Sleep onset latency
Subjective time duration, in minutes, between the time the participant attempts to fall asleep (e.g., lights off, lying in bed) and the time they perceive they have fallen asleep.
Subjective wake after sleep onset
The perceived total duration, in minutes, of all periods of wakefulness occurring after initial sleep onset and before final awakening
Subjective Total sleep time
The perceived total duration, in minutes, of actual sleep obtained during the night, excluding periods of wakefulness.
