All selected studies comprised case\u2013control studies and presented fair quality. Contrary to our hypothesis, HD patients showed impairment only in categorization skills in comparison with controls, particularly at confidence to complete categorization tasks. Regarding attention, episodic memory, working memory, information-processing speed, planning, decision-making, inhibitory control, mental flexibility, language, and visuospatial ability, HD patients did not show impairment when compared with controls. There is a paucity of studies on social cognition in HD patients, although they may show deficits. The impact of emotion in cognition is also understudied in HD patients.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec id=\"S1092852922000153_sec4\" sec-type=\"conclusions\">\n                    <jats:title>Conclusion<\/jats:title>\n                    <jats:p>Except for categorization skills, the cognitive performance in HD patients does not seem to be impaired when compared with that in controls.
