Explore the regions of the brain, their functions, and how injury affects every part of life — for survivors and the families who love them.
The largest lobe of the brain, governing personality, reasoning, and voluntary movement. It is the most commonly injured region in traumatic brain injuries, which is why personality changes are so often reported after TBI.

Each region of the brain has a distinct role. Understanding these roles helps explain why brain injuries can affect so many different aspects of a person's life.
The largest lobe of the brain, the frontal lobe governs our most human qualities — personality, decision-making, emotional regulation, and voluntary movement. It is the most commonly injured region in traumatic brain injuries, which is why personality changes are so often reported after TBI.
Processes sensory information from the body — touch, temperature, and pain — and helps us understand our position in space. Damage can affect reading, writing, and the ability to navigate familiar environments.
Critical for forming and retrieving memories, understanding spoken language, and processing sounds. Injury here often causes memory loss, language difficulties, and changes in emotional behavior.
The brain's dedicated visual processing center. Damage can result in partial or complete vision loss, difficulty recognizing faces or objects, and visual disturbances even when the eyes themselves are undamaged.
Coordinates smooth, precise movement and maintains balance. Injury can cause tremors, loss of coordination, and difficulty with fine motor tasks like writing, buttoning clothes, or walking steadily.
Controls the most fundamental life functions — breathing, heart rate, blood pressure, and the sleep-wake cycle. Brain stem injuries are among the most severe and can affect consciousness itself.
Brain injury reaches far beyond the individual. It reshapes relationships, challenges mental health, and touches every member of a family.
A brain injury can fundamentally alter how a person thinks, moves, and experiences the world. Memory loss — both short-term and long-term — is one of the most common and disorienting effects, leaving survivors struggling to retain new information or recall familiar faces and events.
Physical impairments such as weakness, paralysis, chronic headaches, and fatigue can make everyday tasks exhausting. Many survivors also experience changes in personality and emotional regulation, becoming more impulsive, irritable, or withdrawn — not by choice, but because the brain regions that govern these functions have been damaged.
Cognitive challenges including difficulty concentrating, slowed processing speed, and problems with planning or problem-solving can make returning to work or school feel impossible. These invisible symptoms are often the hardest for others to understand.
The psychological toll of a brain injury is profound and often underestimated. Depression and anxiety are among the most common mental health consequences, affecting up to 50% of survivors. These conditions can arise both from the neurological changes caused by the injury and from the emotional weight of loss.
Many survivors experience a grief for their former self — a mourning of the person they were before the injury. This identity crisis can be deeply isolating, especially when the changes are invisible to others. Post-traumatic stress disorder (PTSD) is also common, particularly when the injury resulted from a violent accident or assault.
The path to mental health recovery after brain injury requires specialized support. Standard therapies may need to be adapted to account for cognitive challenges. Patience, professional guidance, and peer support from others who truly understand the experience are all essential components of healing.
Brain injury does not happen to one person — it happens to an entire family. Spouses, parents, children, and siblings are suddenly thrust into the role of caregiver, often without preparation, training, or adequate support. Caregiver burnout is extremely common, as the demands of care can be relentless and emotionally draining.
Relationships are tested in ways that few can anticipate. The person you love may seem like a different person after their injury — and in some ways, they are. Navigating this new reality while grieving the relationship you had requires enormous emotional resilience and often professional counseling.
Children in the family are particularly vulnerable. They may not fully understand what has happened, and they often internalize the stress and grief of the household. Financial strain from medical bills, lost income, and ongoing care costs adds another layer of pressure that can push families to their breaking point.
Yet families also demonstrate extraordinary strength. With the right resources, community, and support, families can adapt, grow, and find new ways to connect and thrive together.
