Study Notes

Amnesia and Brain Damage

Amnesia typically arises from bilateral brain damage; however, unilateral damage can also lead to amnesia.
The left hemisphere is more crucial than the right for the development of amnesia.

Functional Disorders

Functional disorders lack clear brain disease but may involve subtle, cellular-level brain changes.
Traditionally categorized as neuroses (with insight, partial personality involvement, intact reality testing) and psychoses (lack of insight, widespread personality distortion, false environments).
Recent understanding acknowledges that patients with neurotic disorders may lack insight, while psychotic patients may seek help.

Symptomatology of Mood Disorders

Key symptoms for depressive episodes include loss of self-esteem, excessive guilt, thoughts of death, diminished concentration, altered psychomotor activity, sleep disturbances, and appetite changes.
Moderate depressive episodes require the presence of defined criteria, including several key symptoms.

Classification of Depressive Episodes

Severe depressive episodes without psychotic symptoms (F32.2) require all three core symptoms and additional symptoms leading to an overarching total.
Severe depressive episodes with psychotic symptoms (F32.3) include the criteria for severe episodes but necessitate hallucinations or delusions without meeting schizophrenia criteria.

Diagnostic Tools

SCAN (Schedules for Clinical Assessment in Neuropsychiatry) is a structured interview approach used for diagnosis, relying on symptom ratings rather than clinical judgment.
CIDI (Composite International Diagnostic Interview) is a standardized interview suitable for non-clinicians, requiring no clinical judgment.
Both diagnostic methods utilize algorithms to classify symptoms according to DSM-IV or ICD-10.

Hallucinations

Hallucinatory experiences in schizophrenia can vary in quality, with voices that may provide directives or commentary on the individual's actions.
Auditory hallucinations may present as neutral, abusive, or even benign, and can affect the patient's behavior significantly.
Concepts such as Gedankenlautwerden (thought echo) are described, signaling the phenomenon of hearing one’s thoughts vocalized.

Phantom Limb and Perception

Phantom sensations may arise post-surgery, illustrating discrepancies between the phantom and previous limb appearance.
The perception of phantom limbs can diminish over time, with distal sensations fading faster than proximal ones.

Patient Experience with Hallucinations

Patients experiencing organic hallucinations often exhibit fear and suspiciousness, potentially leading to harmful behaviors.
In depressive states, patients may experience curiously-focused voices that reinforce negative self-perceptions and suicidal thoughts, often without accompanying fear.
