Motor-Cognitive Training for Motoric Cognitive Risk Syndrome

The goal of this clinical trial is to investigate if combined motor-cognitive training can improve motor and cognitive symptoms in older adults with motoric cognitive risk syndrome. The main questions it aims to answer are: * Does motor-cognitive training using a virtual reality treadmill improve gait speed? * Does motor-cognitive training using a virtual reality treadmill improve cognitive functions? Researchers will compare virtual reality treadmill training with treadmill training to see if virtual reality treadmill training works to improve motor and cognitive functions in older adults at risk of dementia Participants will * Complete 18 sessions (1 hour, 3x/week, 6 weeks) of either virtual reality treadmill training or treadmill training * Complete a pre- and post-training assessment * Wear an activity sensor for seven days prior to the pre-training assessment and for seven days after the post-training assessment.

Inclusion Criteria: * Age ≥ 65 * English speaking * Normal cognition (CDR=0) * Meet MCR criteria * Voluntary consent Exclusion Criteria: * Major chronic unstable disease or neurological condition (e.g., seizures) * Diagnosed dementia * Active psychiatric conditions * Musculoskeletal conditions that affect walking for more than 2 minutes * Severe visual or hearing impairments * Sedating drugs (new use of narcotics or anxiolytics within the past month or chronic use that causes sedation) * Currently engaged in other non-pharmacological interventions to improve cognition or walking
