When dementia changes a parent, adult children often learn to love through adaptation: meeting the person who is present instead of demanding the parent they remember. Dementia—cognitive loss severe enough to disrupt daily life—can also affect emotional control and personality, shifting love toward reassurance, protection, and practical care. This change can bring tenderness, anger, guilt, and grief at the same time. The task is not to deny those losses, but to separate illness-driven behavior from intention and decide what care you can sustainably provide.

Is the change actually dementia?
Behavior or mood changes alone do not establish dementia. The National Institute on Aging's overview of dementia explains that clinicians assess medical history, cognition, medicines, laboratory results, and possible psychiatric or other treatable contributors. Write down specific changes before an appointment.
Note what happened, when it began, how often it occurs, and whether it interferes with familiar tasks. "She became difficult" is less useful than "She missed three bill payments and became confused while making breakfast." Ask the clinician what the evaluation has ruled out and what remains uncertain. A diagnosis may explain troubling behavior, but it should follow an assessment rather than a family assumption.
Separate the symptom from the relationship
Dementia can change memory, thinking, emotional control, and social behavior. A parent who becomes suspicious, blunt, withdrawn, or repetitive may be responding from an impaired brain rather than making a deliberate statement about the relationship. That distinction can change the adult child's response. If a parent insists that nobody called, proving the phone record may deepen the conflict. A calmer response might be, "You've felt alone today.
I'm here now." An explanation is not an obligation to absorb every hurt. If an interaction becomes degrading or unsafe, step away, shorten the visit, or bring another person into the care routine. Understanding the illness and setting a boundary can happen together. This reframing may be harder when the relationship was painful before dementia. Adult children do not need to rewrite family history to provide humane care. Love may mean arranging appropriate help rather than personally performing every task.
Make room for grief before death
Pre-death grief is mourning losses that occur while someone is still alive. An adult child may grieve a parent's memory, judgment, affection, advice, or ability to recognize a shared past. A systematic review of 55 studies, mostly involving spouses and adult children, found that pre-death grief is well documented.
Greater caregiver burden and depression were associated with higher grief, while evidence about service use remained limited, according to the review in International Psychogeriatrics. Grief can exist alongside love and even relief. Naming the exact loss—"I miss asking Dad for advice"—is often more manageable than treating the entire experience as one unnamed sadness. It also helps identify what remains possible, such as sharing music, sitting together, or completing a familiar ritual.
Turn love into workable actions
Choose a realistic purpose for each interaction. One visit might be about companionship; another may be about completing a meal or preparing for an appointment.
Expecting every encounter to restore the old relationship creates a test neither person can reliably pass. During difficult moments: Keep brief notes about what settles or overwhelms your parent. A pattern such as quieter visits in the morning or distress during rushed tasks can guide future plans and give the care team more concrete information.
- Use one short question or request at a time.
- Respond to the feeling when correcting a harmless detail serves no practical purpose.
- Offer two manageable choices instead of an open-ended decision.
- Break a task into the next visible step.
- Pause or leave when either person becomes too distressed to continue.
Decide what you can carry
Caregiving should not depend on guilt alone. Consider your health, finances, job, children, distance, and history with the parent. Decide which tasks you can perform, which require another relative or paid help, and which need professional oversight. Support can help without fixing everything.
A meta-analysis of 22 telehealth studies involving 2,132 caregivers found modest improvements in burden, depression, and stress, but no significant improvement in anxiety, according to Aging & Mental Health. That makes remote support a reasonable option to try, not a guaranteed solution. Tell your own clinician when caregiving is affecting your physical or mental health. At your parent's next appointment, ask who can discuss support groups, respite care, and care-partner needs. For detailed planning, work through the relevant chapters in the NIA guide to caring for a person with Alzheimer's disease and write down one task to delegate this week.
