5. Assessment - Classification Flashcards
What are the two main contemporary classification systems in psychiatry?
ICD 10 and DSM IV
What is an operationalised approach?
the use of precise clinical descriptions of disorders, together with predefined exclusion and inclusion criteria and details of the number and duration of symptoms required for diagnosis
What are characteristic symptoms?
symptoms pertinent to a diagnosis, such as the symptoms of depression
What are discriminating symptoms?
are necessary for diagnosis since they are not found in other disorders
What are pathognomonic symptoms?
symptoms which strongly favour one diagnosis over another and have high specificity for the diagnosis
What are inclusion and exclusion criteria?
a hierarchy of symptoms, arranged in order of importance, forming the core inclusion and exclusion criteria used to establish a diagnosis
What is the atheoretical approach?
diseases are described according to the observed phenomenology, not an understanding of what might be causing the disease
What is the descriptive approach?
classification of illness based on what constitutes the illness, rather than what causes it
What are the advantages and disadvantages of a categorical approach?
Easy to understand
Based on existing knowledge base
Easy communication
Poor validity - vague catagories
What are the advantages and disadvantages of a dimensional approach?
More valid given continnum of emotional and cognitive states Can indicate severity Comorbid diagnosis difficult Good for research Unclear clinical utility
What is hierarchical organisation?
certain disorders take precedence over others when making a diagnosis (Jasperian theory) - ICD 10 still uses this system with organic disorders at the top of the hierarchy
What is a multiaxial approach?
provides a holistic assessment of the individual in terms of their disorder and functioning
What multi-axial approach is used in ICD-10?
Axis 1: the mental disorder
Axis 2: the degree of disability
Axis 3: current psychosocial problems
What multi-axial approach is used in DSM-IV?
Axis 1: Clinical disorders
Axis 2: Personality Disorders/Mental retardation
Axis 3: General Medical Conditions
Axis 4: Psychosocial and Environmental problems
Axis 5: Global Assessment of Functioning
What assessment instruments have been developed using the ICD10?

- No nocturnal increase in dysfunction
- Attention and concentration more well preserved
- ‘Don’t know’ answers are common in testing
- Memory loss for remote events more severe than recent ones
What are the diagnostic criteria for dementia?
- Global deterioration in intellectual capacity and disturbance in higher cortical functions like memory, thinking, orientation, comprehension, calculation, language, learning abilities and judgement, an appreciable decline in intellectual functioning and some interference with personal activities of daily living
- Insidious onset with slow deterioration
- The absence of clinical evidence or findings from individual investigations suggestive of organic brain disease or other systemic abnormalities
- Absence of sudden onset or physical/neurological signs

What are the diagnostic criteria for vascular dementia?
- Presence of a dementia syndrome, defined by cognitive decline from a previously higher level of functioning and manifested by impairment of memory and two, or more, cognitive domains and deficits should be severe enough to interfere with ADLs, not due to the physical effects of stroke alone
- Onset may follow a cerebrovascular event and is more acute
- The course is usually step-wise, with periods of intervening stability
- Focal neurological signs and symptoms or neurological evidence of cerebrovascular disease judged aetiologically related to the disturbance (hemiparesis, lower facial weakness, Babinski sign, sensory deficit, hemianopia, dysarthria) or neurological imaging
- Emotional and personality changes are typically early, followed by cognitive deficits that are often fluctuating in severity
- Symptoms not occurring during the course of delirium
What are the diagnostic criteria for dementia with Lewy Bodies?
- Spontaneous motor features of Parkinsonism
- Fluctuating cognition with notable variation in attention and alertness
- Recurrent visual hallucination, which are typically well formed and detailed
- A progressive cognitive decline that is severe enough to interfere with normal social and occupational functioning and memory loss may not be an early feature, but it is usually evident with progression
- Supportive features: neuroleptic sensitivity and history of falls
What is Parkinson’s disease dementia?
Parkinsonian symptoms existed for 12 months before dementia developed
If cognitive and motor symptoms develop within the same 12 month period then a diagnosis of Lewy Body dementia is given
