Examination and Disturbance of Attention and Concentration (MSE)

1. Overview & Definitions

In the Debrecen psychopathology framework, attention is "the ability to focus on the matter in hand. It selects among stimuli — it is the filter of the mind." It is examined as part of the sensorium / cognitive block of the MSE, immediately after consciousness and orientation, and before memory and intellect — because if attention is broken, every test that follows is unreliable.

Characteristics of attention (Dr. Gajdos / TOK):

⚠️ Debrecen-specific definition — examiners insist on this. Here tenacity = how long you can stay on a target and vigilance = how easily you can move off it. This is the opposite of the loose US usage where "vigilance" means sustained watching. Use the lecture's pairing (below), not the colloquial one.

• Concentration = the effortful, sustained application of attention to a task (high tenacity, resisting distraction). Practically: attention held over time against competing stimuli.
• Distractibility = pathologically high vigilance — attention is captured by every irrelevant stimulus and cannot be held (low tenacity).

Attention vs. memory (an examiner's favourite trap): Attention is the gate into encoding; memory is storage and retrieval. If a patient cannot register a stimulus (poor attention), it never enters memory — so they will fail a memory test for a reason that is not a memory disorder. Always clear attention first: in classic amnestic syndrome (e.g. Korsakoff) attention/digit span is normal but new learning fails; in delirium attention itself is broken, contaminating every memory item.
