Symptoms of Schizoaffective Disorder
The presentation of schizoaffective disorder can vary widely between individuals. It involves a complex interplay of psychotic symptoms and mood episodes.
Key Takeaways
- —Three distinct symptom categories: positive (psychotic), mood, and negative symptoms.
- —Auditory hallucinations (hearing voices) are the most common psychotic symptom — voices may comment, command, or converse.
- —Negative symptoms — avolition, alogia, anhedonia, flat affect — are often the most functionally disabling over the long term.
- —Manic symptoms occur in the bipolar subtype only; depressive symptoms occur in both subtypes.
- —Symptom severity and presentation vary significantly between individuals and over the course of the illness.
Psychotic Symptoms
These are often referred to as "positive symptoms," meaning they represent added behaviors or experiences that are not typically present.
Hallucinations
Experiencing sensations that aren't grounded in reality. Auditory hallucinations (hearing voices) are the most common, but they can be visual, tactile, or olfactory.
Delusions
Fixed, false beliefs that persist despite evidence to the contrary. Examples include paranoia or beliefs that one has special powers or significance.
Disorganized Thinking & Speech
Difficulty organizing thoughts, which may manifest as disjointed speech, rapid topic shifts (derailment), or using words that don't make logical sense together.
Mood Episode Symptoms
Depending on the subtype, individuals experience profound shifts in emotional states.
Manic Symptoms
- Elevated, expansive, or irritable mood
- Decreased need for sleep
- Racing thoughts and rapid speech
- Increased activity or agitation
- Impulsive or risky behavior
Depressive Symptoms
- Persistent feelings of sadness or emptiness
- Loss of interest in previously enjoyed activities
- Significant changes in appetite or weight
- Fatigue or loss of energy
- Feelings of worthlessness or guilt
Negative Symptoms
"Negative" symptoms refer to an absence or reduction of typical emotional responses or thought processes. They are often less dramatic than psychotic symptoms but can deeply impact daily functioning.
Avolition
Lack of drive or motivation to initiate activities.
Alogia
Poverty of speech; saying very little or providing brief replies.
Anhedonia
Inability to experience pleasure from positive events.
Affective Flattening
Reduced expression of emotion via facial expressions or voice tone.
