Question 21

What is ecoligical validity?

Answer 21

It refers to how well the neuropsychological assessment data refelcts everyday functioning, or predict future behaviour or behavioral outcomes.

Question 22

What are the 6 examination purposes which may prompt a neuropsychological examination

Answer 22

1. Diagnosis
2. Patients care and planning
3. Treatment planning
4. Treatment evaluation
5. Research
6. Forensic neuropsychology

Question 23

What is an important aspect of diagnosis?

Answer 23

Screening

Question 24

What is clinical neuropsychology?

Answer 24

Clinical neuropsychology is an applied science focused on the behavioral expression of brain dysfunction.

Fun fact: Neuropsychological programs were created for the First World War (WW-I) for screening and diagnosis of brain injured and behavioral disturbed servicemen and for their rehabilitation afterwards.

Question 25

Which three domains contributed to the development of clinical neuropsychology?

Answer 25

(1) clinical neuroscience; (2) educational psychology (tried to measure intelligence); (3) experimental studies of cognitive functions in both humans and other animals.

Question 26

What is an epileptic seizure?

Answer 26

An epileptic seizure is a sudden, transient alteration in behavior caused by an abnormal, excessive electrical discharge in the brain due to a temporary synchronization of neuronal activity occurring for reasons which are not clearly understood

Question 27

What are provoked seizures?

Answer 27

Provoked seizures may occur with high fever, alcohol or drug use, alcohol or drug withdrawal, metabolic disorders, or brain infections

Question 28

The diagnosis of epilepsy requires the presence of at least two unprovoked seizures. The main clinical signs and symptoms of epilepsy include? (common EEG patterns)

Answer 28

Ictal (during a seizure), postictal (immediately following a seizure), and interictal (between seizures) manifestation

Question 29

Seizures can be focal or generalized. Generalized can be characterized in three major categories:

Answer 29

- Idiopathic epilepsies: have no known etiology and usually are not associated with any other neurological disorders; many of these patients do not have neuropsychological deficits - Cryptogenic epilepsy: etiologies are unknown, but neurological and neuropsychological functions are usually not normal - Symptomatic epilepsy: a known etiology

Question 30

What are focal or partial seizures?

Answer 30

Partial seizures: also called ‘focal’ or ‘localization-related’ – arise from a specific area of the brain, may be simple, and may involve only one mode of expression (motor, somatosensory, autonomic, or psychic).

Question 31

What are generalized seizures?

Answer 31

Generalized seizures: involve all or large portions of both hemispheres beginning at seizure onset.

Question 32

Burler and Zeman propose three types of memory impairments in epilepsy

Answer 32

- Transient epileptic amnesia, in which the principal manifestation of seizures is recurrent episodes of amnesia - Accelerated long-term forgetting, in which newly learned memories are forgotten over days and weeks after acquisition - Remote memory impairment, in which memories from the distant past are lost
