There are times in life when people quietly say, “I just don’t feel like myself anymore.” This experience can be deeply unsettling, not only for the individual but also for family members who witness subtle changes in personality, emotional expression, motivation and behaviour. Although this state is often described as “feeling lost,” it does not necessarily mean that a person’s identity has disappeared. More often, it reflects a temporary disruption in the complex interaction between the brain, mind, body, and environment.
From a psychological perspective, our sense of self is not fixed; it is continuously shaped by our thoughts, emotions, relationships, physical health, and life experiences. During periods of prolonged stress, illness, grief, caregiving responsibilities, major life transitions, or aging, this delicate balance can become disrupted. Individuals may begin to feel emotionally detached, less engaged with life, uncertain about themselves, or disconnected from the qualities that once defined them. Modern neuroscience helps explain why this occurs. Chronic stress activates the body’s stress-response system, increasing the release of cortisol and other stress hormones.
While these responses are essential for coping with short-term challenges, prolonged activation may affect areas of the brain responsible for memory, emotional regulation, decision-making, and motivation. The hippocampus, which supports learning and memory, the amygdala, which process emotions, and the frontal cortex, which governs planning, judgement, and self-control, may all be influenced when stress becomes persistent. As a result, individuals may have trouble concentrating, reduced confidence, emotional numbness, indecisiveness or a diminished sense of purpose.
Psychologist often describe this experience as a disturbance in one’s self-concept or personal identity rather than a permanent loss of self. People may recognise that something has changed within them but struggle to explain exactly what it is. They may withdraw socially. Lose interest in previously enjoyable activities, express fewer emotions, or feel disconnected from their surroundings. Family members frequently notice these changes before the individual fully recognises them. Importantly, these experiences shouldn’t automatically be interpreted as signs of irreversible decline.
One of the most encouraging discoveries in neuroscience is the concept of neuroplasticity – the brain’s remarkable ability to adapt, reorganise, and form new neural connections throughout life. Although recovery may occur gradually, the brain retains an extraordinary capacity to heal, and compensate when supported by healthy lifestyle choices, meaningful social relationships, appropriate medical care, and positive psychological interventions.
Research also highlights the importance of cognitive reserve, the brain’s resilience developed through lifelong learning, social engagement, physical activity, and mentally stimulating experiences. Individuals who continue to challenge their minds, maintain strong social connections, and participate in purposeful activities often demonstrate greater resilience when facing stress or age-related changes. While cognitive reserve does not prevent every illness, it can strengthen the brain’s ability to adapt and function effectively despite adversity.
The husband of 41-year-old woman described noticing gradual changes in his wife following a prolonged period of emotional and physical stress. She became quieter, less expressive, and appeared emotionally distant. Conversations became limited, and she often seemed uncertain about her surroundings. Rather than responding with frustration, he chose patience, reassurance, and gentle companionship.
Over several weeks, he observed encouraging signs of improvement, began asking meaningful questions again, showed greater awareness of her environment, and her facial expressions gradually reflected more emotion and engagement. Although her recovery remained incomplete, these subtle improvements illustrated an important principle: when underlying causes are recognised and appropriate support is provided, the journey back to oneself often begins with small but meaningful steps.
Recovery is rarely dramatic. More commonly, it unfolds gradually through tiny changes that accumulate over time. Improved eye contact, renewed curiosity, spontaneous conversation, increased emotional responsiveness, better sleep, greater participation in daily routines, and renewed enjoyment of familiar activities are often early indicators that healing is taking place. Families should celebrate these seemingly small milestones, as they frequently signal positive changes occurring within the brain and emotional wellbeing. At the same time, persistent or worsening symptoms should never be ignored. Ongoing changes in memory, personality, behaviour, orientation, or emotional functioning may reflect underlying medical or psychological conditions that require professional assessment. There are many physical and neurological conditions that resemble a loss of self. Early recognition and timely intervention often improve outcomes significantly.
Scientific Perspective: The concepts discussed in this article are supported by contemporary research in neuroscience, psychology, gerontology, and lifestyle medicine. Current evidence demonstrates that chronic stress, prolonged inflammation, inadequate sleep, social isolation and physical inactivity can influence brain function, emotional regulation, and cognitive health. Conversely, neuroplasticity, cognitive reserve, regular physical activity, social engagement, quality sleep, balanced nutrition and meaningful purpose have all been associated with improved psychological wellbeing and healthier aging.
