Manage Dementia And Sexually Inappropriate Behavior

People with dementia experience symptoms caused by changes in the brain that affect cognitive impairment, emotions, and behaviors. Providing dementia care can be especially challenging because of these symptoms. 

One of the more troubling behavior changes that caregivers sometimes see is inappropriate sexual behaviour. Dementia patients may say things, do things, or touch people in ways that are not appropriate. This behavior can be upsetting and difficult to manage as a family member or caregiver. 

In this article, we’ll:

• Explain why it happens
• Give examples of inappropriate behaviors
• Discuss helpful ways to manage these behaviors

Dementia, Sex, & Intimacy

Intimacy and sex often change with age, but especially when one partner has dementia. Dementia causes cognitive decline as well as significant emotional, behavioral, and physical changes that affect intimacy. Each partner may become more or less interested in sex. 

The partner with dementia may express interest in sex and intimacy more openly, with less inhibition. The other partner may worry about issues of consent. Someone with dementia may have reduced empathy, which affects how they relate to their partner. 

Many couples continue to enjoy intimacy after a dementia diagnosis, but in different ways. It’s an important issue to discuss and to approach with an open mind. 

How Does Dementia Affect Sexual Behaviours? 

Dementia can affect sexual behaviors in different ways, depending on the type of dementia, medications, and other factors. Their attitude or feelings toward sex can also change in unpredictable ways. 

These are some examples of common changes: 

• Changes in Sexual Desire: Someone with dementia may have more or less sexual desire or interest in sex.
• Sexual Performance Issues: They may not be able to perform sexually at all.
• Altered Partner Interactions: Dementia patients often react differently toward their intimate partner, often seeming to be insensitive or lacking empathy.
• Sexual Disinhibition: Dementia causes sexual disinhibition in many patients, which causes them to say or do inappropriate things.
• Public or Social Inappropriate Behaviors: When someone with dementia displays inappropriate behaviors, it can be with caregivers, family and friends, strangers, or even in public.
• Sexual Aggression: A dementia patient may even become sexually aggressive.

Why Does Dementia Change Sex & Intimacy?

Because dementia is a brain disorder, it affects many different emotions and behaviours. These include sexual feelings and behaviours related to sex. Dementia generally causes disinhibition, which can take many forms, including sexual behaviours. 

Disinhibition and sexually inappropriate behaviors are especially common in frontotemporal dementia (FTD). This is a type of dementia with changes in the brain’s frontal and temporal lobes. These changes affect language, speech, personality, and behavior. 

Several aspects of dementia cause changes in sex and intimacy, disinhibition, and inappropriate sexual behaviour. For example: 

• Misinterpretation of Actions: It’s easier for someone with dementia to misinterpret someone else’s actions or behaviours. This can lead to misunderstandings and sexual inappropriateness, especially with caregivers who often must provide hands-on personal care. They might mistake appropriate care for sexual advances. 
• Confusion of Identities: A dementia patient can also become confused about other people’s identities due to memory loss and other symptoms. They may mistake someone for their partner and show inappropriate sexual interest. 
• Difficulty Communicating Needs: Dementia patients often struggle to communicate their needs and feelings. A desire for closeness or non-sexual intimacy can be difficult to express and may be misunderstood by others.
• Other Communication Mistakes: For example, touching that seems inappropriate or like sexual activity may actually be the patient trying to communicate that they need to use the bathroom. A patient may take off their clothing because they are too warm or uncomfortable, not realizing that doing so is inappropriate. 
• Medication Effects: Medications may affect a patient’s sexual behaviors by boosting their sex drive or causing more aggression. 

How To Manage Inappropriate Sexual Behaviour

Sexually inappropriate behavior is one of the most difficult aspects of care for caregivers and loved ones of dementia patients. This is especially true for family caregivers seeing their parents, spouses, or other loved ones behaving in disturbing ways. 

Inappropriate sexual expression and behaviors cannot be ignored. They’re harmful to your loved one and those around them. Address and manage these behaviors early and as needed to find effective solutions. 

How To Respond In The Moment

There are many ways to approach inappropriate sexual behavior, but it’s often most difficult to know how to respond in the moment. 

How you react will depend on the unique situation, but these tips can help: 

• Remain Calm: Try to remember that they might not understand that what they’re doing is inappropriate. 
• Provide Privacy. If possible, and depending on the type of behavior, provide privacy. Get your care recipient into a bathroom or somewhere away from others. 
• Offer Distraction: Distraction can be a powerful tool for someone with dementia who is distressed or exhibiting problematic behaviors. Offer them an activity to do or ask for their help with a chore they can manage. 
• Protect Others: Protect other people around you if necessary by moving your care recipient away from them. 
• Remove Others (if needed): If you cannot get them out of the situation, you may be able to remove others by asking them to leave. 
• State Unacceptability Firmly: If they still don’t stop, tell your loved one their behavior is unacceptable. Be gentle and kind but firm, and ask them to stop. 
• Explain Personal Care: If they have misunderstood your touch while providing personal care, calmly explain what you’re doing and why. 
• Call Emergency Assistance: Call for emergency assistance if your loved one has become aggressive or violent to the point that you fear they may harm you, someone else, or themselves. 
• Note Triggers: Write down anything that might have triggered the inappropriate behavior so you can avoid it in the future. 

In addition to these general tips, it helps to know how to react in specific situations. Continue reading for more examples. 

If They Make Sexual Comments Or Jokes

Resist the urge to scold your loved one for saying inappropriate things. Calmly explain to them why they cannot say things like that. Distract them with other activities or change the subject to talk about something else they’re interested in. If a stranger was involved, you could apologize and also explain why it happened. 

If They Touch Themselves Or Remove Their Clothing

You can try to stop this type of behavior by explaining why it isn’t appropriate, but this might not help. Try to remove your loved one from the situation as quickly as you can. Try to distract them with another activity. 

If removing clothing is an issue, try to determine the root cause. Ask yourself:

• Are the clothes itchy? 
• Are they too warm? 
• Are they wet or soiled?

If the behavior persists, provide clothing that is difficult for them to remove. 

If They Make Sexual Advances

Gently explain to your loved one that their sexual interest is not appropriate and not wanted. Again, you can use distraction, but be firm about stopping the behavior. It can be very distressing for whoever is the object of the advances. Remove your care recipient from the area if necessary. 

If They Make Sexual Demands

The caregiver may be the subject of inappropriate behavior, but this can be more complicated if you’re also their spouse. Your sexual relationship has likely changed, but your partner doesn’t always remember this.

You don’t have to give in to their demands simply because you are married or partners. Be respectful, kind, and firm about what you want and don’t want. Distraction from the situation can help, but you might need to remove yourself and give them space for a little while. 

If you’re not the partner of your care recipient, they might confuse you with their spouse or a past partner. Gently remind them who you are and that you’re not that person. 

Talk To Your Loved One’s Medical Team

Talk to your loved one’s doctor or other members of the medical team if you’re struggling to manage sexually inappropriate behaviors. They can:

• Suggest solutions
• Help you identify triggers or underlying causes
• Determine or rule out any medical issues

There is no accepted medical treatment for inappropriate sexual behavior in patients with dementia. In cases where it persists and is causing serious issues, doctors may consider medications to help control and reduce the behaviors. 

Studies have found that SSRI antidepressants can be useful because lowered libido is a common side effect. SSRIs have lower risks of adverse effects compared to other medications that might help. They’re often the first choice when other, non-medical treatments or therapies don’t reduce unwanted behaviors. 

Studies also show some positive benefits with hormonal agents. These medications lower or block testosterone and other hormones to lower libido. Antipsychotic medications can also lower libido, but they cause significant side effects in many patients. 

No medications are specifically approved to treat inappropriate sexual behavior, but doctors can use them for this purpose at their discretion. It’s important ot remember that this should be a last resort due to the potential for side effects or interactions with other medications. 

Preventing Inappropriate Behaviour

Patients with dementia often act inappropriately (both sexually and non-sexually) in response to discomfort, medications, confusion, and other factors related to their condition. Caregivers can reduce the risks of inappropriate behaviours with stability, routines, and overall good care. 

Maintain A Routine

Changes to routine can be particularly upsetting and confusing for someone with dementia. Familiarity and routine are comforting and calming because they struggle to react to changes and disruptions. 

Maintain a daily routine for your loved one and strive to keep a consistent structure throughout the day whenever possible. They’ll respond and behave more predictably when they know what to expect. They will be less likely to lash out or act inappropriately due to discomfort or distress. 

Create A Calm Environment

A calm environment can prevent distress and resulting difficult behaviors. Keep the number of visitors at a minimum. Keep the home or care environment quiet. Use types of stimuli that you know will calm your loved one, such as favorite music or movies. Calming scents can also help. 

Encourage Healthy Habits

Maintaining healthy habits helps your loved one feel better. Sleep is particularly important. Encourage them to get enough sleep every night and to take naps as needed. Being tired can quickly lead to frustration and aggression. 

As much exercise as is possible and safe will also help your loved one feel calmer. Physical activity provides an outlet for excess energy and frustration. A walk in the park, group classes, and opportunities to engage with others are all helpful. 

Keep Them Busy & Socially Engaged

Inappropriate behaviors can result from boredom or loneliness. Spend as much quality time with your loved one as you can, doing activities with them that they enjoy. Provide appropriate and comforting touch. 

Dementia patients can become lonely if they live at home instead of in assisted living or memory care with others. Arrange for visitors and look for other opportunities for socialization, such as events at adult day care centers. 

Stay Up To Date With Medical Care

Regular medical care is essential for keeping your care recipient as healthy and comfortable as possible. It can be difficult for someone with dementia to communicate that they don’t feel well or are in pain. Regular medical care helps you stay on top of any secondary issues that arise, like infections or depression.

Regular care also helps you manage their dementia as effectively as possible. Your loved one’s condition will continue to worsen. Their symptoms and needs change. Their interventions and treatments should evolve with these changes. 

Inappropriate behaviors and even sexual aggression are not uncommon in patients with dementia. These changes can be upsetting and difficult for caregivers to manage. To keep everyone safe and comfortable, these issues must be addressed. If you’re struggling, contact your loved one’s medical team for advice and guidance.
