Negative SymptomsCurrent Lecture Psychosis- Represents a basic break from reality- A person w/ psychosis is deemed to be “psychotic” - Major diagnosed psychotic disorder- paranoid schizophrenia - Psychosis vs. neurosis (thinking based on reality for the most part) Psychotic Conditions- Involve psychotic episodeso Borderline personality disordero Schizotypal personality disorder o Schizoaffective personality disordero Bipolar disorder (ie manic depression)o Severe major depressive disordero A “purer” form of psychosis is witnessed w/ schizophrenia These notes represent a detailed interpretation of the professor’s lecture.

Schizophrenia- NOT “D.I.D.”—Dissociative identity disorder - Literally means “split mind” but NOT a splitting of personality - Eugene bleuler coined the term in an effort to capture the fracturing of the pt’s cognitions and emotions and the severe disorganization this condition caused in their mental worlds - Demographicso Affects 1% of population, worldwideo Represented in ALL societies o Affects roughly equal # of men and women o Typically diagnosed in late teens-late twentieso Tends to be diagnosed slightly LATER in females than in maleso Paranoid schizophrenia= most COMMONLY DIAGNOSED SUBTYBE- Adolescence and Onseto Symptoms show up in following sequence: 1) Negative symptoms (i.e. social withdrawal) 2) Cognitive symptoms (i.e. grades drop) 3) Positive symptoms (ie hallucinations and delusions)—something being added/excessed compared to healthy people - **Usually 3-5 years after the very first problems were noticed o It has become apparent that brain changed during adolescence somehow triggers the devp’t of schiz. But it is not well understood what specifically goes awryo In NORMAL adolescence, 1% of cortical grey matter is lost to “pruning”o This is doubled in adolescents that will go on to develop schiz.o Most prominent in the PFC Symptomology- Hallucinationso Perceptions not based on physical stimulation of the sensory system(s)o **SENSORY PERCEPTUAL o Auditory is the most commono Visual is not so common (unlike in the movies)o May occur in ANY sensory modality -Delusionso Beliefs that clearly contradict realityo Main categoriesDelusions of persecutions, grandeur, control (being controlled) and ideas of referenceCannot change a person’s mind no matter how long you talk to them and try to sway them otherwise -Thought Disorderso (Categorized as positive, technically)o Irrational, often illogicalo More “loose” and general than delusionso Schizophrenics have trouble, fo ex, distinguishing btw plausible and absurd conclusions o Schizophasia- utterances (random words/sentences put together, not clearly making sense—aphasia) -Negative symptoms = lackso Flattened/blunted affecto Poverty of speech (alogia)o Lack of motivation, initiative persistence o Inability to experience pleasure (anhedonia)o Social withdrawal/isolation o Cognitive and neg symptoms appear to be attributable to deficiencies in the same brain regions (DLPFC region)Glutamate and dopamine are not as active in these
