Title: Randomized Controlled Trial of Community-based Nutritional, Physical and Cognitive Training Intervention Programmes for At Risk Frail Elderly
Brief Summary: The aims of this proposed community-based randomized controlled trial are to evaluate the effectiveness of nutritional, physical exercise and cognitive training interventions for at-risk and frail elderly, to elucidate the biological determinants and changes associated with frailty, and to develop, evaluate and demonstrate the feasibility of screening instruments for frailty.


Options:
A: Inclusion Criteria:

* Age 65 or older
* Mini-Mental State Examination (MMSE) score 23 or greater
* Vision scored greater than 20/50
* Minimal dependence in hygiene, bathing, and dressing

Exclusion Criteria:

* Significant decline in cognitive skills, physical abilities, or functional independence
* Inability to complete study activities as evidenced by MMSE and vision scores lower than Inclusion Criteria requirement
* Diagnosis of Alzheimer's disease
* Stroke in previous 12 months
* Cancer with limited life expectance
* Current chemotherapy or radiation treatment
* Communication problems
* Planned move from study area
* Scheduling conflicts that would preclude participation in study activities
* Prior involvement in similar cognitive training studies
B: Inclusion criteria for patients with MCI

1. Patients fulfilling criteria for AMCI \[Petersen et al. 2001b\]:

   i. Memory impairment for age and education ii. No impairment in other cognitive domains iii. Normal social activities iv. Patient is not demented
2. For the other subtypes of MCI, cognitive impairment in one or more nonmemory domain
3. Sedentary lifestyle with no regular participation in physical exercise defined as two or three times a week for at least 20 minutes duration, or participation in active sport more than once a week, in the previous six months.
4. Willing and able to give informed consent.
5. Availability and access to safe exercise environments, such as paths or roads with sidewalks for walking or cycling.
6. At low risk from serious adverse effects from increased physical activity as indicated by performance on the revised Physical activity readiness questionnaire (PARQ).

Exclusion Criteria:

Exclusion criteria for patients with MCI

1. Type 1 (insulin dependent) diabetes mellitus.
2. Blood pressure of 160/100 mmHg or more.
3. Body weight more than 140% of ideal body weight.
4. Musculoskeletal or other medical problems preventing safe participation in regular moderate intensity exercise (65-77% of predicted maximum heart rate). This will include a resting tachycardia (heart rate above 100 bpm) and history of myocardial infarction or unstable angina within the last month.

Participants with modifiable exclusion criteria will be reconsidered after successful management. Patients will be referred for medical treatment prior to commencing exercise if indicated by the PARQ and the intervention will be guided by the PARmedX.

Participants taking medications affecting heart rate will need to be on a stable dosing regime for 3 months prior to commencing in order to control for potential spurious results on fitness measures caused by these treatments.
C: Inclusion Criteria:

1. Age of 65 years or older
2. Living at home
3. Able to walk without personal assistance and no other physical limitations that can limit participation and adherence, particularly to exercise intervention programme
4. Meet criteria for frailty

Operational definition of frailty.

The participants are assessed and classified on the level of frailty by the following measures and criteria:

1. Weight loss
2. Slowness
3. Poor balance and weakness assessed by chair stand test
4. Muscle weakness assessed by hand grip and knee extension strength
5. Exhaustion, fatigue or low endurance
6. Low physical activity

Exclusion Criteria:

1. Member of household already enrolled
2. Dementia or cognitive impairment, major depression or other psychotic disorders
3. Severe audio-visual impairment
4. Progressive, degenerative neurologic disease like Parkinsonism, fits/ epilepsy, etc
5. Rapidly progressive or terminal illness under palliative care with life expectancy less than 12 months
6. History of alcohol abuse or any other substance abuse
7. Severely affect muscle/joint dysfunction resulting in disability
8. Hospital admission in the past 3 months
9. Regular physical training or physiotherapy or current participation in a vigorous exercise or weight-training program more than once per week
10. Undergoing therapeutic diet incompatible with nutritional supplementation
11. In the opinion of research clinician, the intervention is deemed to be potentially hazardous for the subject, such as serious cardiac and pulmonary disease.
D: Inclusion Criteria:

* 50 years of age or older
* Patient of the FCC in Family Medicine or General Internal Medicine Clinic at UIHC
* No known memory problems

Exclusion Criteria:

* Significant vision impairments
* Lack of access to a computer or owns a MAC
* Lives more than 37 miles from the lab
* Traumatic Brain Injury or severe stroke
