Recognizing the early signs of psychosis
Psychosis rarely begins overnight. In most cases, there is a period of gradual change — sometimes called the prodrome or clinical high-risk state — where subtle shifts in thinking, perception, and behavior emerge weeks or months before a full episode. Recognizing these changes early is one of the most important things anyone can do, because early intervention dramatically improves outcomes.

Important context
Many of these signs — taken individually — are common in adolescence and young adulthood and can have other explanations (stress, sleep deprivation, substance use, depression, anxiety). What matters is the pattern: multiple changes occurring together, persisting over time, and representing a clear departure from how the person usually thinks, feels, and behaves. When in doubt, an evaluation by a mental health professional is always worthwhile — and being wrong is far better than missing something.
Changes in thinking
These are often the earliest and most subtle signs — easy to dismiss as stress, daydreaming, or “just a phase.”
- Difficulty concentrating, following conversations, or organizing thoughts
- Feeling like thoughts are speeding up or slowing down
- Trouble distinguishing between what is real and what is imagined
- New or unusual ideas that feel intensely meaningful or significant
- Suspiciousness or feeling watched, followed, or talked about
- Feeling like messages on TV, in music, or online are directed at you
Changes in perception
Perceptual changes can be subtle at first — brief anomalies that the person may not mention because they seem too strange to talk about.
- Hearing sounds, voices, or whispers that others don't hear — even briefly
- Seeing shadows, shapes, or movements at the edges of vision
- Feeling like familiar places or people look strange or unfamiliar
- Heightened or distorted senses — colors seem too bright, sounds too loud
- Feeling disconnected from your own body or surroundings
Changes in behavior and daily functioning
Friends and family often notice these changes before the person experiencing them does.
- Withdrawing from friends, family, and activities you used to enjoy
- Decline in school or work performance — especially if sudden
- Neglecting personal hygiene or self-care
- Unusual sleep patterns — sleeping far too much or staying up for days
- Speaking in ways that others find hard to follow
- Emotional flatness or responses that seem out of proportion
- Increased anxiety, irritability, or mood swings
Why timing matters
Researchers use the term Duration of Untreated Psychosis (DUP) — the time between the start of psychotic symptoms and the start of treatment. Studies consistently show that a shorter DUP is associated with better response to treatment, faster symptom improvement, and better long-term functioning. The goal is not to cause alarm, but to encourage action: if you notice these changes in yourself or someone you care about, reaching out to a mental health professional sooner rather than later is one of the most helpful things you can do.
What to do if you notice these signs
If you’re noticing changes in yourself
- Talk to someone you trust — a friend, family member, or counselor
- See your primary care provider or a mental health professional
- Call 988 or NH Rapid Response (833-710-6477) if you're in distress
- Know that seeking help is a sign of strength, not weakness
If you’re noticing changes in someone else
- Express concern without judgment — "I've noticed some changes and I care about you"
- Don't try to argue about what's real — focus on how they're feeling
- Encourage a conversation with a provider; offer to go with them
- If there's immediate danger, call 988 or go to the nearest ER
