PTSD in older adults and veterans

Post-traumatic stress disorder (PTSD) is a lasting reaction to a frightening or dangerous event. It can bring nightmares, unwanted memories, jumpiness and a strong urge to avoid reminders. PTSD can affect people at any age. Older adults are less likely to have it than younger adults, but it still happens, and it may look different later in life.¹

Some older adults first notice symptoms decades after a war or other trauma. Others have lived with symptoms quietly for years. This page explains why old memories can return, what we know about Korean War and Vietnam veterans, where veterans and families can get help, and how PTSD and dementia are connected.

Why PTSD can look different later in life

PTSD may be less common in older adults for several reasons. Many have built strong coping skills over a lifetime. Some people with severe PTSD died younger. And PTSD did not become an official diagnosis until 1980, so many older people were never checked for it.¹

Many older adults also grew up in a time when people were expected to keep problems to themselves. Because of this, they may describe their distress as body problems instead. Common examples are poor sleep, stomach trouble, aches or feeling tense. Doctors may not think to ask about trauma.^1,7 Older adults are also less often sent for a mental health check.¹

PTSD in later life can follow a few different paths:^1,2

• Long-lasting. Symptoms began after the trauma and never fully went away.
• Coming and going. Symptoms faded, then returned during hard times.
• Late onset. Symptoms showed up for the first time many years after the event.
• New trauma in later life. PTSD can start after a trauma in older age, such as a serious fall, a crime, a disaster or a stay in intensive care. See who develops PTSD.

Some older adults have a few PTSD symptoms but not enough for a full diagnosis. This "partial" PTSD may be about as common as full PTSD in older veterans, and it can still make life harder.²

When old memories come back: late-onset stress symptomatology

Researchers who study aging combat veterans noticed a pattern. Some veterans coped well for decades. Then, in later life, war memories began to come back more often, sometimes with distress.^3,4 They named this late-onset stress symptomatology, or LOSS.

Life changes that come with aging seem to set it off. These include:^1,4

• Retirement. Work kept the mind busy. More free time can leave room for memories.
• Loss. Losing a husband, wife, friends or fellow veterans can bring grief and loneliness.
• Health problems. Pain, serious illness, less ability to move around, or changes in thinking and memory.
• Life review. Older age is a natural time to look back. Quiet time and reflection can bring up the past.
• Reminders. News of wars, anniversaries, reunions or funerals with military honors.

In more recent work, the same researchers renamed this process later-adulthood trauma reengagement (LATR). They dropped the word "symptomatology" because it can sound like an illness. Going back over old memories is not always a problem. It can be part of making sense of one's life.^3,4

LATR can go two ways:^3,4

This is different from PTSD in an important way. A person with PTSD usually tries hard to avoid memories. A person in LATR is more likely to face them and think them through.⁴

The VA has a questionnaire called the LOSS Scale. It is for male combat veterans 55 and older and asks how much they agree with statements about re-examining their war experiences. There is also a shorter 11-question version that takes about 3 minutes. It can help a provider decide whether to ask more questions.³

Korean War veterans

The Korean War lasted from June 1950 to July 1953. It is sometimes called "the forgotten war."⁷ Most veterans of that war are now in their 90s.

During and after the war, doctors used terms like "combat fatigue." The main goal was to return soldiers to duty. Long-term effects were mostly ignored for decades.⁷ Reports from that era describe symptoms we now link to PTSD: nightmares, anger, a strong startle reaction and pulling away from others.⁷

Studies from the 1990s and early 2000s found that Korean War combat veterans had more PTSD and more severe symptoms than World War II combat veterans, though less than Vietnam veterans. Former prisoners of war had some of the hardest experiences.⁷ Many of these men were raised to be stoic, and many never had treatment.⁷

Vietnam War veterans

Most Vietnam War veterans are now in their 70s and 80s. The best long-term look at their health is the National Vietnam Veterans Longitudinal Study. It followed veterans for about 40 years after the war.⁶

What it found, in plain numbers:⁶

• About 1 in 9 men who served in the war zone still had full or partial war-related PTSD about 40 years later.
• The researchers estimated that about 271,000 Vietnam war-zone veterans had current PTSD (full or partial).
• About 1 in 3 of those veterans also had major depression.
• Over time, symptoms got worse in about 16% of war-zone veterans and better in about 8%. Getting worse was about twice as common as getting better.

This shows that war-related PTSD does not always fade with time. For some veterans, it grows stronger with age.

How common is PTSD among veterans?

The VA reports these rates from a large national study. The numbers include only veterans who were still alive when the study was done.⁵

PTSD and dementia

PTSD and dementia are linked in two directions.

PTSD raises the risk of dementia. A 2020 review pooled 8 studies with about 1.7 million people. People with PTSD were about 1.6 times as likely to develop dementia as people without it. The risk was similar in veterans.⁸ Most of these studies looked back at health records, so they cannot prove that PTSD causes dementia.⁸ PTSD is also linked to heart disease and diabetes, which affect brain health too.² Researchers do not yet know whether treating PTSD lowers dementia risk.⁸

Dementia can bring PTSD symptoms back. Memory loss and changes in thinking are among the life changes that can stir up war memories.⁴ People who have lived with PTSD for a long time may find it harder to keep old memories contained in later life.⁴

In a study of veterans in long-term care, families and staff said PTSD symptoms with dementia were "the same but different." Distrust, aggression and nightmares often became stronger and harder to manage. Care was more complex. Building trust and knowing the veteran's life story made a real difference.⁹

Treatment works at any age

Trauma-focused therapy can help older adults. Studies in older adults show symptoms improve, and most people complete treatment.² Moderate evidence The evidence has limits. Few people over 75 have been studied.² Learn about the main options on our trauma-focused therapies page, including cognitive processing therapy and prolonged exposure.

Memory problems are not always a barrier. Mild or moderate memory loss usually does not rule out PTSD treatment.² The therapist may use large print, speak clearly and go at a steady pace. When it helps, a family member may join some sessions, but the therapist still speaks to the person first.² Video visits can help people who have trouble getting to appointments.^1,2

Medicines need extra care. Older adults can be more sensitive to side effects and drug interactions. Doctors usually start low, go slow and change one medicine at a time.² Benzodiazepines (sedatives such as lorazepam or alprazolam) are not recommended for PTSD. They should be avoided in older adults because they raise the risk of falls, confusion and slowed breathing.² Talk with your doctor or pharmacist before changing anything. See medicines for PTSD and medicines that can affect mood and memory.

Looking back with support. For veterans going through LATR, researchers suggest guided life review, education about retirement and other changes, and peer groups with other veterans.⁴ See reminiscence and life review.

Daily coping. Staying connected, volunteering and group activities help many older adults.¹ The VA also offers a PTSD Coach app with self-help tools.¹ Read coping with trauma symptoms, retirement and mental health and try the grounding practice.

VA help for veterans and families

Facts below are current as of October 2026. Programs and phone numbers can change.

VA PTSD care. VA has almost 200 PTSD treatment programs across the country. They offer assessment, talk therapy, medicine, group therapy and family therapy.

Call VA at 800-827-1000 (weekdays, 8 a.m. to 9 p.m. Eastern) for help.¹⁰

Vet Centers. There are about 300 Vet Centers in communities across the country, plus mobile centers that travel to rural areas.^10,11 They offer free, private counseling in a relaxed, non-medical setting. Services include individual, group, couples and family counseling, and grief counseling.¹¹ Veterans who served in a combat zone can use them, and so can their families.^10,11 The Vet Center Call Center at 877-927-8387 is open 24 hours a day.¹¹

Disability compensation. Some veterans with PTSD linked to their service can get monthly VA disability payments.¹⁰

Help for family caregivers. The VA Caregiver Support Program helps caregivers of veterans enrolled in VA health care, from any service era. It offers skills training, coaching, peer support and links to local help.¹² A second program adds a monthly payment and more services, but only for veterans with a service-connected disability rating of 70% or higher who meet other rules.¹² Call the Caregiver Support Line at 855-260-3274 (weekdays, 8 a.m. to 8 p.m. Eastern).¹² For dementia care help, see VA benefits for dementia.

When to get help

Talk with a doctor or mental health provider if you or someone you love:

• Has nightmares, flashbacks or upsetting memories that are new or getting worse
• Avoids people, places or news that bring back the past
• Seems on edge, angry, or jumpy at loud noises
• Is drinking more, sleeping poorly or pulling away from family
• Has memory changes along with fear, distrust or reliving the past

Ask for a short PTSD screening. Many clinics use a short screening called the PC-PTSD-5.² Read getting assessed for PTSD and finding geriatric mental health care. If you are supporting someone, see supporting someone with PTSD and caregiver burnout.
