Which of the following ADHD medications is not a stimulant?

A. Delusions are a positive symptom of schizophrenia, not a negative symptom. They are false, fixed beliefs that persist despite evidence to the contrary. Common types include persecutory, grandiose, and bizarre delusions. Positive symptoms result from excess dopamine activity in the mesolimbic pathway.

B. Avolition is a negative symptom characterized by a lack of motivation to initiate and sustain goal-directed activities. It leads to difficulties with personal hygiene, work, and social engagement, significantly impairing daily functioning.

C. Apathy is a negative symptom marked by a lack of interest, enthusiasm, or emotional responsiveness. Individuals with schizophrenia may show indifference to social interactions, personal achievements, or daily activities.

D. Alogia (poverty of speech) is a negative symptom where individuals speak less and provide minimal verbal responses. This reflects impaired thought processing and reduced cognitive engagement, common in schizophrenia's mesocortical dopamine pathway dysfunction.

A. Meaningless rhythm of words. This describes word salad, a disorganized speech pattern where words are strung together without logical connection, often seen in schizophrenia or severe psychosis.

B. Roundabout. This refers to circumstantial speech, where an individual provides excessive, unnecessary details before eventually arriving at the main point. This is commonly seen in mania, obsessive-compulsive disorder (OCD), or cognitive impairment.

C. Made-up words. Neologisms are newly invented words or phrases that have no meaning to others but may carry personal significance to the individual. This is frequently observed in schizophrenia, psychotic disorders, or neurological conditions like aphasia.

D. Repeating of another's words. This describes echolalia, a speech disturbance where a person repeats words or phrases spoken by others, often seen in autism spectrum disorder (ASD), schizophrenia, or catatonia.
