A Comprehensive Geriatric Assessment (CGA) is a structured and multidimensional evaluation designed to assess the medical, functional, cognitive, psychological, and social needs of elderly individuals. It is a widely used tool in the UK healthcare system, particularly in NHS geriatric services, primary care, and care homes.
CGA is essential for identifying frailty, mobility limitations, chronic conditions, cognitive impairments, and social care needs. This assessment enables healthcare professionals to create a personalized care plan aimed at improving quality of life, independence, and long-term health outcomes.
This article provides a detailed breakdown of the key components of a Comprehensive Geriatric Assessment, outlining the methods used and the role of each evaluation in elderly care.

A Comprehensive Geriatric Assessment (CGA) in the UK typically includes the following five core components:
- Medical Assessment – Identifies existing illnesses, medication management, and overall health status.
- Functional Assessment – Evaluates daily living activities and mobility.
- Cognitive Assessment – Assesses memory, attention, and executive function.
- Psychological Assessment – Identifies depression, anxiety, and emotional well-being.
- Social Assessment – Examines living conditions, social support, and care requirements.
The multidisciplinary approach used in CGA ensures that all aspects of an elderly person’s well-being are considered when developing a tailored care plan.
Comprehensive Geriatric Assessment: A Detailed Breakdown
| Assessment Category | Key Areas Evaluated | Commonly Used Assessment Tools |
|---|---|---|
| Medical Assessment | Chronic diseases, frailty, medication review, nutritional status | Frailty Index, Medication Reconciliation, Blood Tests |
| Functional Assessment | Mobility, ability to perform daily tasks (ADLs, IADLs) | Barthel Index, Katz Index, Timed Up and Go (TUG) Test |
| Cognitive Assessment | Memory, problem-solving, risk of dementia | Mini-Mental State Examination (MMSE), Montreal Cognitive Assessment (MoCA) |
| Psychological Assessment | Depression, anxiety, emotional well-being | Geriatric Depression Scale (GDS), Patient Health Questionnaire (PHQ-9) |
| Social Assessment | Living conditions, family support, access to care services | Social Support Survey, Housing and Care Needs Evaluation |
1. Medical Assessment
The medical evaluation in CGA focuses on identifying chronic diseases, medication side effects, nutritional status, and frailty. Healthcare professionals use blood tests, physical examinations, and medication reviews to assess overall health and the risk of complications.
Key Factors Evaluated:
- Frailty screening to detect vulnerability to illness and falls.
- Medication review to assess polypharmacy and adverse drug interactions.
- Chronic disease management for conditions such as diabetes, cardiovascular diseases, and osteoporosis.
2. Functional Assessment
The functional component of CGA determines an elderly individual's ability to perform daily activities independently. This includes both basic activities of daily living (ADLs) and instrumental activities of daily living (IADLs).
Key Factors Evaluated:
- Mobility and gait stability to assess the risk of falls.
- Ability to perform personal care tasks such as dressing, bathing, and eating.
- Capacity for complex daily activities such as cooking, managing finances, and using transportation.
3. Cognitive Assessment
A cognitive evaluation is performed to detect dementia, memory loss, and executive function deficits. Early diagnosis of Alzheimer’s disease and other neurodegenerative conditions can significantly improve care planning.
Key Factors Evaluated:
- Memory and recall ability using the Mini-Mental State Examination (MMSE).
- Cognitive flexibility and executive function using the Montreal Cognitive Assessment (MoCA).
- Dementia risk and early signs through GPCOG screening.
4. Psychological Assessment
Mental health is a critical component of elderly care, as depression and anxiety are common in older adults, particularly those with limited mobility or social isolation.
Key Factors Evaluated:
- Depression and mood disorders using the Geriatric Depression Scale (GDS).
- Anxiety and stress levels through standardized mental health questionnaires.
- Emotional well-being and coping mechanisms.
5. Social Assessment
The social evaluation in CGA examines the elderly person’s living conditions, family support, and access to community care services. This component ensures that the individual has adequate resources to maintain independence and well-being.
Key Factors Evaluated:
- Housing conditions and whether modifications are needed.
- Family and caregiver support to prevent neglect or isolation.
- Availability of social services, including home care assistance and community programs.
