45. Abnormalities of Thought Processes Circumstaniality Indirection and delay in reaching a point because of unnecessary detail. Loose Associations Person shifts from one unrelated subject to another. Flight of Ideas Almost continuous flow of accelerated speech with abrupt topic changes. Incoherence Incomprehensible because of illogic, lack of meaningful connections, abrupt topic changes, or disordered word use/grammar. Confabulation Fabrication of facts or events to fill in gaps in impaired memory. Perseveration Persistent repetition of words or ideas. Echolalia Repetition of the words or phrases of others. Neologisms Invented or distorted words. Blocking Sudden interruption in mid-sentence or before completion of an idea. Clanging Person chooses a word based on sound instead of meaning.
46. Abnormalities of Thought Content Obsessions Recurrent, uncontrollable thoughts, images, or impulses that a persons considers unacceptable or strange Compulsions Repetitive acts that a person feels driven to perform to prevent or produce some unrealistic future state of affairs. Delusions False, fixed, personal beliefs that are not shared by other members of the person’s culture. Phobias Persistent, irrational fears; accompanied by a compelling desire to avoid the stimulus. Anxieties Apprehensions, fears, or tensions that may be free-floating or focused (i.e. phobia). Feelings of Unreality A sense that things in the environment are strange, unreal, or remote. Feelings of Depersonalization A sense that one’s self is different, changed, or unreal. Identity is lost.
56. Testing for Aphasia Word Comprehension Comprehension of spoken language through recognition (“point to your nose”) or understanding (“Can dogs fly?”). Repetition Repeat items of increasing complexity. Note the fluency and accuracy of the responses. Naming Name a series of objects or colors. Gradually increase difficulty. Note the fluency and accuracy of the responses. Reading Comprehension Have the patient follow several simple written commands. Writing Ask the patient to make up and write a sentence.
