Definition: A disorder characterized by impairment of memory, learning difficulties, and reduced ability to concentrate on a task for more than brief periods. There is often a marked feeling of mental fatigue when mental tasks are attempted, and new learning is found to be subjectively difficult even when objectively successful. None of these symptoms is so severe that a diagnosis of either dementia (F00-F03) or delirium (F05.-) can be made. This diagnosis should be made only in association with a specified physical disorder, and should not be made in the presence of any of t ...[+++]he mental or behavioural disorders classified to F10-F99. The disorder may precede, accompany, or follow a wide variety of infections and physical disorders, both cerebral and systemic, but direct evidence of cerebral involvement is not necessarily present. It can be differentiated from postencephalitic syndrome (F07.1) and postconcussional syndrome (F07.2) by its different etiology, more restricted range of generally milder symptoms, and usually shorter duration.

In Finland, for example, the financial decision-making system in the regions was simplified at the beginning of the new period, concentrating most ERDF, ESF, EAGGF and FIFG decisions under one umbrella agency ('one-stop-shop').

Cohesion Fund assistance during the previous programming period concentrated heavily on the Greater Lisbon, Greater Oporto and Algarve regions, in an attempt to clear the backlog in these more heavily populated areas and comply with Community Directives 80/778/EEC and 98/83/EC.

Thanks to assistance from the Fund, which, particularly at the beginning of the period, concentrated quite heavily (29% of Portugal's 'quota'), on road transport, the Lisbon-Madrid and Lisbon-La Coruña routes could be completed and construction of the Lisbon-Valladolid route speeded up.

During the 1991 to 1999 period, concentration levels in the trucking industry in Canada actually decreased.
