schizophrenia spectrum and other psychotic disorders Flashcards
Sensations of restlessness, pacing, and an inability to sit still.
akathisia
The inability to recognize objects by touch.
asteorognosis
An exaggerated, robotic cooperation with requests.
automatic obedience
Lack of motivation.
avolition
False belief based on incorrect inference or perception.
delusions
Spastic contractions of muscle groups.
dystonia
The repetition of words spoken by another.
echolalia
The compulsive imitation of another’s actions.
echopraxia
The ability to order sequential behaviors, establish goal-directed plans, and monitor personal behavior.
executive functioning
are common in patients treated with first-generation antipsychotic medications and third generation during the initiation phase (Stahl, 2017). are caused by an imbalance between dopamine and acetylcholine in the extrapyramidal system of the basal ganglia. As such, the symptoms involve the systemic motor system. Side effects may be acute or chronic.
extrapyramidal symptoms (eps)
Often referred to as symptoms of disorganization, ` describes a lack of progressive goal-directed thought processes (related to the severity of neurobiological deficits) that manifest in abnormal/odd speech, affecting overall communication; symptoms include loose associations, tangentiality, incoherence/word salad/neologism, illogicality, circumstantiality, pressured/distractible speech, and poverty of speech.
formal thought disorder
Abnormal perceptual (visual, auditory, olfactory, gustatory, and tactile) experience that occurs without external stimuli.
hallucination
Neurological signs/symptoms that indicate impaired reflex, sensory, or motor functioning and are localized to a particular brain region; examples include hypoalgesia, impaired olfactory functioning, and oculomotor abnormalities.
hard signs
Affects and behaviors that are diminished or absent in patients with schizophrenic spectrum disorders; these include having a flat or blunted affect, thought blocking, poverty of speech (alogia), avolition, and social withdrawal.
negative symptoms
Typically associated with schizophrenic spectrum disorders, symptoms that involve additions to normal experiences and include hallucinations and delusions as well as abnormal movements and problems with speech (formal thought disorder).
positive symptoms
Prior to onset of symptoms.
premorbid
A symptomatic period prior to the diagnosis of SSDs that represents a definite change from premorbid functioning, is clearly identified as problematic, and continues until the emergence of psychotic symptoms.
prodorme
A symptom of mental illness characterized by distorted perceptions of reality, marked changes in personality, and greatly impaired functioning.
psychosis
Producing a condition resembling psychosis.
psychotomimetic
Characterized by major mood symptoms (depression, mania, or both) occurring during most of the same period of illness as delusions or hallucinations and lasting at least 2 weeks.
schizoaffective disorder
A disturbance lasting at least 6 months (if untreated) that consists of at least two major positive or negative symptoms; one of the cardinal symptoms must be either delusions, hallucinations, or disorganized speech.
schizophrenia
Neurological deficits that do not implicate a specific brain area. include grimacing, increased blink rates, problems sequencing motor tasks, and astereognosis.
soft signs
A movement disorder characterized by involuntary, repetitive movements, often associated with neuroleptic therapy and advanced age.
tardive dyskinesia
A tendency to remain immobile.
waxy flexibility
