Parkinson’s and your mind: mood, worry and thinking changes

Parkinson’s touches feelings and thinking as well as movement, and those changes deserve care too.

By the numbers

How common mood and thinking changes are in Parkinson’s.

Mind and mood

50%+of people with Parkinson’s will have some form of depression along the way.
Up to 40%will have an anxiety disorder.
20–50%will have mild changes in thinking, and not all of them go on to develop dementia.
20–40%report hallucinations or delusions.

United States

1.1 million+people in the U.S. live with Parkinson’s.
~90,000people in the U.S. are diagnosed each year.

World

8.5 million+people worldwide had Parkinson’s in 2019, and the number has doubled in 25 years.

Mood, depression and anxiety together affect wellbeing in Parkinson’s even more than common movement symptoms. That makes them worth raising at every visit.

Why Parkinson’s affects your mind

It’s brain chemistry, not weakness.

Parkinson’s affects brain areas that make dopamine, serotonin and norepinephrine. These chemicals help control mood, energy, motivation, appetite and sleep.

Depression or anxiety can appear early, sometimes even before movement problems begin. So these feelings are part of the condition, not a failure to cope.

⚗️ Brain changesThe same changes that affect movement.
Read more

Anxiety and depression in Parkinson’s are linked to the same brain changes that cause tremor and stiffness. They are a treatable part of Parkinson’s.

💭 Living with uncertaintyNot knowing what’s ahead.
Read more

Managing symptoms and facing the unknown can lead to worry about how things might change during the day or over the years.

🏠 IsolationWhen getting out gets harder.
Read more

Parkinson’s can make it harder to stay active and connected, and isolation can add to anxiety.

😞 GriefSadness about the diagnosis is natural.
Read more

Grief after a diagnosis is a normal reaction. Depression is different: it lasts weeks or longer and colors everything.

See A new Parkinson’s diagnosis: the first months.

Depression in Parkinson’s

Common, often missed, and treatable.

Depression in Parkinson’s is common but often overlooked and undertreated. It can come and go, and it can make both movement and thinking symptoms worse.

🔀 Why it’s easy to missSymptoms overlap.
Read more

Some signs of depression, like poor sleep and feeling slowed down, are also signs of Parkinson’s. Some experts think depression in Parkinson’s often shows up as frequent, shorter mood changes rather than constant sadness.

🗣️ Raising it with your doctorIf they don’t ask, you can.
Read more

Many movement disorder specialists now ask about depression. If yours doesn’t, bring it up.

You could say

  • “Could I see a counselor or therapist?”
  • “I don’t enjoy things like I used to.”
  • “I’ve felt down most days for a few weeks.”
🧩 A whole-person approachSeveral things together work best.
Read more

The Parkinson’s Foundation recommends a combined approach: counseling, exercise, social support, and treatment decisions made with your doctor.

Talk with your clinical provider about all treatment options. Finding what works can take some time, so hang in there.

Worry, panic and “off” times

When anxiety comes with the ups and downs of symptoms.

Anxiety can look like ongoing worry, sudden panic, racing thoughts or a sense of dread with no clear cause. It can also bring a pounding heart, sweating or trouble sleeping.

🔄 “Off” periodsAnxiety when symptoms return.
Read more

As treatment wears off between doses, movement symptoms can come back. Some people feel anxious during these “off” times.

If your worry seems to follow a daily pattern, note the times and share them with your clinical provider.

🛋️ Talk therapyUnderstanding and managing anxiety.
Read more

Working with a trained therapist can help you understand your anxiety and find ways to manage it.

🧘 Mindfulness and breathingCalming the body.
Read more

Mindfulness practices and exercise are among the strategies that help manage anxiety in Parkinson’s.

  1. Sit comfortably and rest your hands
  2. Breathe in slowly for four counts
  3. Breathe out for six counts
  4. Repeat five times, noticing your feet on the floor
🍽️ Busy placesPlan for crowds and appointments.
Read more

Group conversations and busy places can feel harder with Parkinson’s. Choosing quieter times and a seat near the exit can ease worry.

Apathy: when motivation fades

Not laziness, and not quite depression.

Apathy means a lack of interest, enthusiasm or motivation. It is a common Parkinson’s symptom, and it can make it harder to exercise or keep to a routine.

Apathy is not the same as depression. Depression often brings guilt or feeling worthless. Apathy can feel more like no mood at all, emotionally flat.

🗓️ Structure does the workDon’t wait to feel like it.
Read more

There are no proven treatments for apathy yet, but structured activities, a regular routine and time with people help.

  • Book exercise with a friend so you’re expected
  • Join a class or group that meets weekly
  • Put small tasks in a calendar with reminders
  • Start with five minutes, then decide
👥 Stay with peopleCompany keeps you engaged.
Read more

Talking with family and friends, or joining a support group, can help you stay engaged and motivated.

💬 For family membersIt’s a symptom, not a choice.
Read more

A person with apathy is not being lazy or making excuses. Gentle structure and doing things together usually works better than pushing.

Thinking and memory changes

Slower thinking, word-finding and focus.

Some people with Parkinson’s notice changes in attention, memory, language or problem-solving. Mild changes may be present at diagnosis, and they often don’t get in the way of home or work life.

Mild thinking changes are not the same as dementia, and not everyone develops dementia. Depression, anxiety, poor sleep and tiredness can all make thinking feel worse.

🗨️ Finding wordsA speech therapist can help.
Read more

Trouble finding the right words is common. A speech therapist can help with language difficulties.

🛠️ Everyday strategiesAn occupational therapist can help.
Read more

An occupational therapist can help you find ways to adapt and cope with thinking changes.

  • Do one thing at a time
  • Keep keys and phone in one spot
  • Plan harder tasks for your best time of day
  • Use a calendar and alarms
🔍 Getting assessedTell your doctor if you’re worried.
Read more

Your doctor may suggest seeing a neurologist or neuropsychologist for testing. Mild changes can be found through testing even when they aren’t noticeable day to day.

See Types of dementia explained if dementia has been mentioned.

Seeing things, vivid dreams and sleep

Perception and sleep changes to always mention.

Some people with Parkinson’s see, hear or feel things that aren’t there (hallucinations). Others misread real things, like seeing clothes in a closet as people (illusions), often in low light.

Tell your care team about any hallucinations or unusual beliefs, even if they don’t bother you. They are manageable, and causes like infection can sometimes be treated.

💡 Good lightingFewer shadows, fewer tricks of the eye.
Read more

Illusions and visual hallucinations tend to happen in low light. Good lighting is one of the supportive steps the Parkinson’s Foundation suggests.

🛏️ Sleep changesNightmares, acting out dreams, daytime sleepiness.
Read more

Common sleep problems include trouble staying asleep, nightmares or very emotional dreams, and feeling drowsy in the day. Some people act out their dreams.

Mention all sleep changes to your care team. Better sleep can also help mood and thinking.

⚠️ When beliefs feel threateningGet help quickly.
Read more

Some people develop fixed false beliefs, such as jealousy or feeling persecuted. If someone feels threatened, they may become agitated or unsafe. Contact the care team promptly, and call 911 if anyone is in danger.

For more on hallucinations in general, see Hallucinations explained: all five senses.

When your face and voice hide your feelings

Masked face and a quieter voice can be misread.

Parkinson’s can mean fewer facial expressions, sometimes called a “masked face.” The voice may become quiet or flat. Others may wrongly think you are bored, cross or sad.

🗣️ Say it out loudLet people know what’s going on.
Read more
  • “If I look serious, I’m not upset. It’s my Parkinson’s.”
  • “My face doesn’t always show it, but I’m really enjoying this.”
  • “Parkinson’s makes my voice quiet. Please ask me to repeat if you need to.”
🎤 Speech therapyHelp for voice and speech.
Read more

Physical, occupational and speech therapies can help with walking, speech and coping with thinking changes.

❤️ For loved onesAsk, don’t assume.
Read more

Instead of reading their face, ask: “How are you feeling about this?” Their words are a better guide than their expression.

What helps your mind

Movement, people, therapy and routine.

🚶 ExerciseGood for mood as well as movement.
Read more

Exercise can ease non-movement symptoms such as depression. People who exercise at least 2.5 hours a week, starting early, have a slower decline in quality of life.

Walking, dancing, yoga, cycling and swimming can all help. Check with your doctor before starting something new.

👥 Support groupsAdvice from people who know.
Read more

Support groups can help with living with Parkinson’s, including its effects on mood. Individual or family counseling can help too.
