The 10\u2009h group also showed improvements in specific areas such as processing speed and recognition. In the 20\u2009h group, the benefits were maintained at 3\u2010 and 6\u2010month follow\u2010ups, especially in functionality.<\/jats:p>\n                  <\/jats:sec>\n                  <jats:sec>\n                    <jats:title>Discussion<\/jats:title>\n                    <jats:p>This study suggests that a higher cumulative dose of DCT may lead to more sustained improvements in functionality performance among older adults with mild neurocognitive disorder.
