What does OCD look like in older adults?

You might think of OCD as something that starts in childhood or early adulthood, and often it does. But it can begin later in life, sometimes triggered by a major life change: retirement, bereavement, a health scare, or moving into supported housing. And sometimes the signs have been there for years, but were put down to something else, being a "worrier", being "particular", or just getting older.

The core of OCD is the same at any age: unwanted, repetitive thoughts (obsessions) that create anxiety, and actions or mental rituals (compulsions) done to try to control that anxiety. But in older adults it can look a little different. You might see someone repeatedly checking they have locked the door, or washing their hands many times a day, or asking the same question over and over. These can look like normal habits or memory lapses, and they often get missed.

Why it gets missed or misdiagnosed

There are several reasons OCD is underdiagnosed in older adults.

One is that the rituals can be mistaken for the routines of old age. A person who checks the stove five times before bed might be seen as careful rather than anxious. Someone who insists on a strict order for their belongings might be labelled "set in their ways".

Another is that the person themselves might not connect their thoughts and behaviours to a condition like OCD. They may have lived with it for decades without a name for it, or they may feel shame about asking for help with something they think they should be able to control.

And sometimes the symptoms are put down to dementia or memory loss. Compulsive questioning, asking the same thing repeatedly, can look like confusion. But the motivation is different. In OCD, the person is driven by anxiety, not by forgetting. They ask because they need certainty, not because they cannot remember the answer.

Signs to watch for

If you are concerned about yourself or someone close to you, here are some signs that could point to OCD rather than ordinary ageing or dementia:

Repeated checking of locks, appliances, taps, or the post
Hoarding objects that have no practical value, driven by a fear of throwing something important away
Intense distress if daily routines are disrupted
Washing or cleaning that goes far beyond what is needed, sometimes to the point of sore skin
Avoiding certain places, people, or situations because of contamination fears
Repeated, anxious questions about health, safety, or whether something bad will happen
Rigid rules about food, medication, or how things are arranged

These behaviours often come with a feeling of shame or secrecy. The person may try to hide them, or make excuses for them. If you notice a pattern, it is worth taking seriously.

The difference from dementia and depression

This is a common worry, and it matters. If you are caring for an older relative, you might see behaviours that look like cognitive decline. But there are important differences.

In dementia, someone might ask the same question because they have forgotten the answer. In OCD, they ask because they cannot tolerate the uncertainty of the answer they already know. They are not confused; they are anxious.

In depression, someone might withdraw from activities because they have no energy or interest. In OCD, they might withdraw because their rituals take up so much time, or because they are afraid of triggers outside the home.

A proper assessment can tell the difference. It is possible for OCD and dementia to coexist, but it is also possible for OCD to be mistaken for dementia, which means a person gets the wrong treatment or none at all.

How to seek an assessment

If you think you or someone you know might have OCD, the first step is a conversation with a GP or family doctor. You can describe what you are seeing without needing a diagnosis in advance. Say something like: "I've been having these thoughts that won't go away, and I find myself doing the same things over and over to feel safe. I'm wondering if it could be OCD."

The doctor can then refer you to a mental health service for a full assessment. In some places, you can also refer yourself directly to an NHS talking therapies service (in the UK) or a similar service in your country. If you are in the US, you can look for a therapist who specialises in OCD. The National Institute of Mental Health (US) has information on finding care.

An assessment usually involves a conversation about your history, your current symptoms, and how they affect your daily life. It is not a test you can pass or fail. It is a way to understand what is happening and what might help.

What treatment looks like for older adults

The main treatment for OCD is a type of therapy called exposure and response prevention, or ERP. It works the same way at any age, though the therapist will adapt it to your life. You might practise facing a feared situation in a gradual way, while learning to resist the compulsion that usually follows. You can read more about how this works in ERP therapy for OCD: how exposure and response prevention works.

Some people also benefit from medication. A doctor can talk through the options, including any interactions with other medicines you might be taking. There is no shame in needing either therapy or medication, or both.

Therapy O'Clock can connect you with therapists who work with older adults, and your GP or local mental health team is another good place to start. If you are caring for someone, organisations like Carers UK offer support for you too.

A note on waswasa and faith

For older adults from Muslim backgrounds, OCD can show up as waswasa, intrusive doubts about worship, purity, or faith. Someone might repeat their prayers many times because they are not sure they did them correctly, or avoid prayer altogether because the doubts feel overwhelming. This is not a lack of faith; it is OCD using faith as its target. You can read more about this in Waswasa and religious OCD: when doubts about worship take over.

How it can look in daily life

Take a man in his late sixties, retired from a job he held for forty years. He starts spending two hours every morning checking the locks, the windows, and the gas hob. He knows it is too much, but if he stops, he feels a wave of dread that something terrible will happen. His wife thinks he is just being thorough. He does not tell her about the dread.

Or a woman of seventy-five whose daughter has noticed she washes her hands twenty times a day. The skin on her hands is cracked. When her daughter asks why, she says she feels dirty. She has not left the house in three weeks.

These are not rare stories. They are the kind of thing that gets dismissed as "just how she is" until someone recognises the pattern.

Getting help is possible at any age

It is never too late to get an accurate diagnosis and effective treatment. Many older adults find that therapy gives them back time and energy they thought they had lost. If you are reading this for yourself, you deserve that. If you are reading it for someone else, your concern is the first step.

You can find therapists who specialise in OCD through the professionals directory. For more on what OCD feels like and how it shows up day to day, see Signs OCD Is Affecting Your Daily Life.

Questions people ask

Can OCD really start for the first time in your 60s or 70s?

Yes. While OCD most often begins in childhood or early adulthood, it can start later in life. A major life event like retirement, a bereavement, or a health problem can trigger it.

How do I know if it is OCD or just normal worrying about health and safety?

The difference is intensity and impact. If worrying takes up hours of your day, stops you from doing things you want to do, or causes you real distress, it is more than normal worry. A professional assessment can help you tell the difference.

My mother asks the same question over and over. Is that OCD or dementia?

It could be either. In dementia, she may genuinely forget the answer. In OCD, she is driven by anxiety and cannot tolerate uncertainty, even if she remembers. A doctor or specialist can help figure out which it is.

What if my father refuses to see a doctor about his rituals?

This is common. He may feel ashamed or think he should handle it alone. You can try talking to him calmly about what you have noticed, without criticism. Offering to go with him to an appointment can help. Sometimes a conversation with a GP first, without him there, is a good starting point.

Can medication for other health conditions cause OCD-like symptoms?

It is uncommon, but some medications can trigger obsessive or compulsive behaviours. If you notice a change after starting a new medicine, mention it to your doctor. They can check whether the medicine might be a factor.

Is ERP therapy suitable for someone with physical health problems or limited mobility?

Yes. A good therapist will adapt ERP to your abilities and circumstances. You do not need to do anything physically demanding. The work is about facing feared thoughts and situations in a gradual, safe way.

My husband has always been a bit rigid about routines. How do I know if it is OCD?

Look for signs of distress. If he becomes very anxious when a routine is broken, or if the routines have become more frequent or intense over time, it might be OCD. Pay attention to whether he seems to be trying to control worry, not just preference.

What if I have been living with these symptoms for decades and never got help?

That is more common than you might think. Many older adults have had OCD for years without a name for it. Treatment works at any age, and people often find relief and a sense of understanding they never had before.

Can OCD get worse after a stroke or a fall?

It can. Any major physical or emotional event can increase anxiety, and OCD often gets worse when anxiety is high. If you notice new or stronger symptoms after an illness or injury, tell your doctor.

Is hoarding a type of OCD?

Hoarding can be a symptom of OCD, but it can also be a separate condition. In OCD, hoarding is often driven by a fear of making a mistake by throwing something away. A professional assessment can tell you which it is and what kind of help you need.

My doctor said it is just anxiety. What should I do?

You can ask for a referral to a specialist who understands OCD. Not all GPs are trained to spot it. You can also look for a therapist who specialises in OCD directly. It is worth getting a second opinion if you feel your experience is not being fully understood.

Can I still practice my faith if I have waswasa?

Yes. Waswasa is the OCD, not the faith. Many people find that working with a therapist who understands both OCD and their religious context helps them separate the intrusive doubts from genuine belief. You can continue your worship while getting treatment.
