Abstract

Rationale: We set out to investigate if subclinical neuropsychological deficits occur in patients with COPD, in psychomotor test not reported in the international literature to our knowledge. Methods: We studied 46 patients with COPD (with normocapnic hypoxaemia) in stable condition (I) and 35 "normals" as the control group (II). Group I had a PaO₂ of 62.3+5mmHg and a PaCO₂ of 42.2+4mmHg. The two groups were matched for their anthropometric characteristics and education and did not have a history of a disease (especially neurologic) other than COPD. They underwent the stress reaction test measuring their body‘s electric resistance and attention concentration in free time. For their evaluation we used devises manufactured by G. Schuhfried GesmbH (Moedling/Austria) for stress reaction, and by G. Ricossay (Paris, France) for the evaluation of attention concentration in free time. Results: The results are expressed as mean (+SD) in the table.
Conclusions: Stress reaction did not show a statistically significant difference while attention concentration did. This finding could be of importance in activities of everyday life like driving and the handling of devises or machines, particularly when these deficits have subclinical character.

Group	Stress reaction (mOhm)	Attention concentration
I	1.8 (0.65)	4.1 (1.01)
II	2.1 (0.62)	2.9 (0.62)
p	0.543 (NS)	< 0.001
