Psychosis is one of the most disorienting experiences in psychiatry — for the person going through it and for the people around them. Hallucinations, delusions, disorganized thinking: these symptoms can emerge suddenly or build gradually, and they’re almost always frightening to witness and hard to understand. A clear evaluation, made early, makes a real difference.
Types of Psychotic Disorders
Psychotic symptoms can appear across several distinct conditions. The primary ones I see in my practice:
- Schizophrenia — a chronic condition characterized by hallucinations, delusions, disorganized thinking, and negative symptoms such as flat affect, social withdrawal, and loss of motivation. It typically emerges in late adolescence or early adulthood and requires long-term management.
- Schizoaffective disorder — a combination of psychotic symptoms and significant mood episodes (depression or mania). The mood component distinguishes it from schizophrenia and shapes how it’s treated.
- Brief psychotic disorder — sudden onset of psychotic symptoms lasting less than a month, often triggered by a severe stressor. Most people recover fully with appropriate support.
- Delusional disorder — fixed false beliefs without the broader symptom picture of schizophrenia. Functioning outside the area of the delusion can appear relatively intact, which sometimes delays recognition.
- Psychosis in mood disorders — both major depression and bipolar disorder can present with psychotic features during severe episodes. In these cases, treating the underlying mood disorder is central.
What Psychotic Symptoms Look Like
Psychiatrists classify psychotic symptoms into three categories:
Positive symptoms — experiences that are present but shouldn’t be: hallucinations (most commonly auditory voices, though visual, tactile, and olfactory hallucinations also occur), delusions (fixed false beliefs, often paranoid in nature), and disorganized thinking (difficulty connecting thoughts, loose associations, tangential speech that family members often notice first).
Negative symptoms — capacities that are diminished or absent: reduced emotional expression, loss of motivation, social withdrawal, decreased speech, and loss of pleasure in activities that previously brought enjoyment. These tend to be subtler than positive symptoms and often respond less robustly to medication.
Cognitive symptoms — impairments in memory, attention, executive function, and processing speed. These can significantly affect daily functioning and are often present even when positive symptoms are well-controlled.
How I Approach Psychotic Disorder Treatment
Treating a psychotic disorder well starts with getting the diagnosis right. That means a thorough evaluation — understanding what’s actually driving the symptoms, ruling out medical causes (thyroid disease, autoimmune conditions, neurological disorders, substance use), and establishing a clear picture before initiating treatment. Psychotic symptoms can have medical explanations that get missed when the workup isn’t thorough enough.
Antipsychotic medication is typically the cornerstone of treatment for primary psychotic disorders. Choosing the right agent matters: different medications have meaningfully different side effect profiles, and tolerability is a major factor in whether someone stays on treatment long enough to benefit. I work carefully with patients and families to find an approach that manages symptoms without creating an intolerable burden.
Medication alone isn’t the whole picture. I involve families in understanding what’s happening and how they can help, coordinate with therapists when cognitive behavioral therapy or family therapy is warranted, and provide close follow-up during the highest-risk periods. Psychotic disorders can be treated effectively — the goal is the best possible quality of life, not just symptom suppression.
I’m Dr. David Brendel, MD, PhD — a Harvard-trained, board-certified private psychiatrist in Belmont, MA, with over 25 years in practice. I was also interviewed in Ravishly on navigating delusions in a loved one — a topic that comes up frequently in my clinical work with families.

Psychotic disorders carry more stigma than almost any other psychiatric condition. That stigma delays diagnosis, discourages people from seeking help, and sometimes means that families are managing a crisis alone for months or years before anyone gets a clear answer about what’s happening.
What I find in my practice is that early, accurate diagnosis and thoughtful medication management make an enormous difference in outcome. Schizophrenia and schizoaffective disorder aren’t the uniformly progressive, deteriorating conditions they’re sometimes portrayed as. With the right treatment, many people stabilize, function well, and lead full lives.
The families who come to me often arrive exhausted — having watched a loved one change in ways they didn’t understand, having tried to help without knowing how. Part of my work is giving those families a framework for understanding what’s happening and a practical sense of what helps. That’s as important as the clinical work with the patient themselves.
