Brief summary
This study aims to investigate the effects of sensory integration training on cognitive functions, quality of life, and social participation in older adults with Mild Cognitive Impairment (MCI)
Detailed description
Sensory impairments are highly prevalent among older adults and have significant effects on the cognitive and functional outcomes of aging. Although the relationship between sensory functions and cognitive processes has been clearly established in the literature, the underlying neurobiological and psychosocial mechanisms of this link are yet to be fully elucidated. In an era of increasing dementia prevalence, older individuals with sensory deficiencies constitute a critical and growing risk group that warrants investigation for a deeper understanding of cognitive aging. Epidemiological data indicate that impairments in visual, auditory, and other individual sensory systems are consistently associated with cognitive decline and the development of dementia. In this context, our study proposes sensory integration training as a potential intervention to bridge the gap between sensory input and cognitive performance.
Interventions
OTHERAerobic Exercise
The aerobic exercise intervention consists of a 12-week outdoor walking program, performed twice weekly for 45 minutes per session at a moderate intensity, targeting a score of 12-14 on the Borg Rating of Perceived Exertion (RPE) scale
The program includes activities that stimulate three main senses: vestibular (balance and movement), proprioceptive (body awareness), and tactile (touch). These exercises are designed to help the brain organize sensory signals more effectively to improve daily functions and cognitive performance.

Inclusion criteria
* Being between 65 and 85 years of age * Having a Montreal Cognitive Assessment (MoCA) score between 18 and 25, indicating mild cognitive impairment * Being in stable medical health, with no history of severe neurological or psychiatric disorders * Voluntary participation
Exclusion criteria
* Clinical diagnosis of dementia or having moderate-to-severe cognitive impairment * Severe visual or hearing loss to a degree that prevents effective communication or participation in assessments * Presence of severe sensory, motor, or physical disabilities that render the intervention (e.g., walking or sensory training) impossible to perform * Acute medical conditions or having unstable chronic diseases that may pose a risk during physical activity.

| Quick Mild Cognitive Impairment Screen - Turkish Version | 6 months | Quick Mild Cognitive Impairment Screen - Turkish Version is a cognitive assessment tool consisting of six sub-headings covering at least five cognitive domains. The sub-headings and the cognitive domains they assess are defined as follows: 1. Orientation: (Questioning the country, year, month, day, and date - approx. 1 minute - 10 points) 2. Registration: (Working memory; repeating 5 given words - 30 seconds - 5 points) 3. Clock Drawing: (Visuospatial; drawing a clock within 1 minute - 15 points) 4. Delayed Recall: (Episodic memory; recalling the 5 previously mentioned words - 30 seconds - 20 points) 5. Verbal Fluency: (Semantic memory/language; naming animals within 1 minute - 20 points) 6. Logical Memory: (Episodic memory; repeating a short story - 1 minute - 30 points) Scoring and Interpretation The test is evaluated out of a total of 100 points, where higher scores indicate better cognitive status. A score of 62 points or below indicates cognitive impairment. |

| World Health Organization Quality of Life - Older Adults Module | 6 months | World Health Organization Quality of Life-Old module is a specialized 24-item instrument designed to evaluate the quality of life in older adults across six distinct domains, utilized via a five-point Likert scale. These domains include sensory abilities, which assesses the impact of sensory functions and their loss on quality of life; autonomy, reflecting independence and the ability to live and make decisions autonomously; past, present, and future activities, which measures satisfaction with life achievements and outlook on the future; social participation, focusing on engagement in daily community activities; death and dying, addressing concerns and anxieties related to the end of life; and intimacy, evaluating the capacity for personal and private relationships. Each item is scored on a scale from 1.0 to 5.0, resulting in potential domain scores ranging from a minimum of 4 to a maximum of 20. A total cumulative score is calculated by summing the individual item v |
| Lubbes Social Network Scale-6 | 6 months | Lubbes Social Network Scale-6 is a specialized instrument comprising six items designed to evaluate the size of a social network, private communication (confiding), and the availability of reciprocal help. The scale is structured into two subscales, with three questions dedicated to family ties and three to friendship networks. Consistent with the original version, each item is rated on a six-point Likert scale ranging from 0 to 5. In this scoring system, individual scores of 0, 1, and 2 indicate a limited or deficient social network, whereas scores of 3, 4, and 5 signify a more extensive and robust social network. The total score is calculated by summing the values of all items, resulting in a range from 0 to 30. Higher total scores on the LSNS-6 are indicative of a greater presence of social network ties and more significant social engagement. |
