What is Adult Failure to Thrive (AFTT)?
While the term "failure to thrive" (FTT) is widely known in pediatrics, it is also a recognized syndrome in geriatric medicine, known as Adult Failure to Thrive (AFTT) [1, 3]. AFTT is a complex condition characterized by a state of overall physical and mental decline in older adults and is not a normal part of aging [2, 3]. It signals underlying issues that require medical attention [2].
AFTT is often described by the presence of interconnected syndromes:
- Impaired Physical Function: Decreased mobility, strength, and overall physical ability [1].
- Malnutrition: Unintentional weight loss, decreased appetite, and poor nutrition [1].
- Depression: Persistent low mood, social withdrawal, and loss of interest in activities [1].
- Cognitive Impairment: Memory loss, confusion, and difficulty with daily tasks [1].
Common Symptoms and Red Flags of AFTT
The symptoms of AFTT can be subtle and develop gradually, often being mistaken for normal signs of aging [2]. Recognizing the specific warning signs is crucial for caregivers and family members [2].
Common signs include:
- Unexplained Weight Loss: A loss of more than 5% of body weight over six months is a significant red flag [2].
- Decreased Physical Activity: A noticeable reduction in movement and energy levels [2].
- Social Withdrawal: Losing interest in previously enjoyed hobbies, friends, and family [2].
- Depression or Low Mood: Symptoms can be masked but include sadness, hopelessness, and lack of motivation [2].
- Cognitive Decline: New or worsening memory problems or confusion [2].
- Poor Immune Function: Increased susceptibility to infections [2].
- Dehydration: Dry skin, confusion, and reduced fluid intake [2].
- Difficulty with Daily Activities: Struggling with basic tasks like bathing and dressing [2].
Underlying Causes of AFTT
The causes of AFTT are almost always multifactorial and require a holistic approach to uncover [1, 3]. The precipitating factors can be categorized into several key areas:
Physical and Medical Causes
Chronic diseases, medication side effects (especially from multiple medications), swallowing difficulties (dysphagia), oral health issues, and sensory impairment can all contribute to AFTT [1, 3].
Psychological and Mental Causes
Depression, anxiety, dementia, delirium, bereavement, and grief can significantly impact appetite and motivation, accelerating decline [1, 3].
Socioenvironmental Causes
Social isolation, poverty, and caregiver fatigue can lead to loneliness, reduced activity, and insufficient support, all contributing to AFTT [1, 3].
The Diagnosis Process: Beyond "Just Getting Old"
Diagnosing AFTT is not a matter of a single test but a thorough, systematic evaluation by a healthcare provider, ideally a geriatric specialist [1, 3].
Evaluation typically involves:
- Comprehensive Medical History and Physical Exam: Reviewing history, medications, and physical condition to identify underlying illnesses [1, 3].
- Nutritional Assessment: Detailed dietary history, weight changes, and blood tests for deficiencies [1, 3].
- Functional Assessment: Evaluating ability to perform activities of daily living (ADLs) and instrumental activities of daily living (IADLs) [1, 3].
- Mental Health and Cognitive Screening: Assessing for depression, anxiety, and dementia using specific tools [1, 3].
- Social and Environmental Review: Assessing living situation, social support, and financial stability [1, 3].
AFTT vs. Normal Aging: A Crucial Comparison
Distinguishing AFTT symptoms from normal aging is vital. Dismissing AFTT as "just getting old" can have severe consequences [2, 3].
| Feature | Normal Aging | Adult Failure to Thrive (AFTT) |
|---|---|---|
| Weight Change | Minor, stable fluctuations. | Unexplained, significant weight loss (over 5%) in 6 months. |
| Energy Levels | General decline in peak energy but maintaining overall activity. | Significant and progressive fatigue and inactivity. |
| Appetite | Generally stable. | Noticeable loss of appetite. |
| Social Engagement | May reduce certain activities but retains social connections. | Withdrawal from social activities, increased isolation. |
| Cognitive Function | Minor, non-debilitating forgetfulness. | Significant memory loss, confusion, affecting daily tasks. |
| Mood | Stable mood. | Persistent depression, sadness, or loss of interest. |
Treatment and Reversing Adult Failure to Thrive
Effective treatment involves a multidisciplinary, individualized approach to address underlying causes [1, 3].
Interventions often include [1, 3]:
- Nutritional Support: Working with a dietitian, possibly using supplements or fortified foods.
- Physical and Occupational Therapy: Exercises to improve strength and mobility, and strategies for daily tasks.
- Mental Health Support: Treating depression and anxiety with counseling or medication, and addressing social isolation.
- Medication Management: Reviewing medications to reduce side effects and interactions.
- Treatment of Underlying Conditions: Managing chronic diseases or other medical problems.

Conclusion
Can failure to thrive happen in adults? Yes, and early recognition is critical [2, 3]. Adult Failure to Thrive is a complex syndrome indicating serious underlying issues, not normal aging [2, 3]. A comprehensive, targeted approach by healthcare professionals can often reverse AFTT, improving quality of life and longevity [1, 3]. If signs of progressive decline are noticed, seeking a thorough medical evaluation is essential [2, 3].
