Phenomenology Flashcards
Mannerism
Odd purposeful movements that are goal-directed. Seen in chronic schizophrenia.
Stereotypy
Non-goal-directed involuntary movements that are carried out repetitively and uniformly. Seen in autism and schizophrenia.
Automatic obedience
Patient does whatever is asked despite being told not to.
Ambitendency
Alternating cooperation and opposition
Echopraxia
Imitates movements of interviewer
Echolalia
Imitates words
Perseveration
Senseless repetition of previously requested movement.
Palilalia
Perseverated word repeated with increasing frequency
Logoclonia
Perseveration of last syllable. Also seen in organic disorders.
Forced grasping
Offered hand grasped despite being told not to. Seen in frontal lobe lesions.
Mitmachen
Body can be put into any posture despite instruction to resist
Mitgehen
Extreme form of mitmachen. Slight passive pressure leads to movement. Associated with forced grasping.
Posturing
Strange postures adopted habitually
Catalepsy
Perseveration of posture. If placed in an awkward position, this position is held.
Waxy flexibility
Smooth resistant muscle tone felt to initial movement
Negativism
Patient does reverse of what is asked. Disorder of volition.
Gegenhelten
Form of negativism. Resistance to passive movement.
Positivism
Echopraxia, mitgehen and automatic obedience.
Apraxia
Disorder of skilled movement, reflects motor system dysfunction at the cortical level.
Ideomotor apraxia
Unable to perform a task to command, even though they are capable of performing the action without prompting.
Limb apraxia
Involves movements of arms/legs
Non-verbal-oral/buccofacial apraxia
Unable to carry out facial movements on command
Ideational apraxia
Difficulty completing a relatively complex motor task, for example, putting toothpaste on a toothbrush.
Limb kinetic apraxia
Unable to make fine precise movements with limbs
Verbal apraxia
Unable to plan movements for speech
Constructional apraxia
Unable to construct pentagons
Oculomotor apraxia
Difficulty with eye movements
Dressing apraxia
Unable to dress self.
Involves non-dominant parietal lobe.
Gerstmann’s syndrome
= dysgraphia/agraphia, dyscalculia/acalculia, finger agnosia, left-right disorientation.
Due to lesion of dominant parietal lobe.
First rank symptoms
- Delusional perception/autochthonous delusion
- Auditory hallucinations - 3rd person AH, running commentary on actions/thoughts, gedankenlautwerden
- Delusions of thought interference - insertion, withdrawal, broadcasting
- Passivity phenomenon
Oneiroid state
Dreamlike state with vivid visual hallucinations.
Can occur in catatonic state in schizophrenia.
Extracampine hallucination
Experienced outside of normal sensory field.
Occur in schizophrenia, epilepsy, organic disease, hypnagogic states.
Lilliputian hallucinations
Small animals/people/fantasy figures.
Can occur in delirium, schizophrenia, seizures, organic disorders, visual disturbance.
Functional hallucination
Generated by an unrelated stimulus in same modality
Reflex hallucination
Generated by unrelated stimulus in a different modality
Palinopsia
Abnormal persistence or recurrence of an image in time.
Seen in organic disease (Parkinson’s).
Autoscopic/heautoscopic hallucinations
Phantom mirror image, can see double of oneself projected into space.
Can occur in depression, schizophrenia, temporal lobe epilepsy, parietal lobe lesions.
Associated with decreased LOC, delirium, narcissism, depersonalisation.
Negative autoscopy
See nothing when looking at oneself in mirror
Double phenomenon/Doppelganger
Subjective phenomenon of doubling
Charles Bonnet syndrome
Complex visual hallucinations which are formed, persisting and repetitive.
No demonstratable psychopathology.
More common in elderly, central/peripheral visual loss.
Insight retained, no delusions.
