Introduction to the Cog-Log

The Cognitive Log (Cog-Log) provides a measure of general cognitive abilities that can be obtained at bedside. The creation of the Cog-Log is in answer to the need for a brief measure of cognition that can document progress during rehabilitation and provide an estimate of skills as assessed by more lengthy evaluations. The Cog-Log can be considered a companion measure to the Orientation-Log. Clinical experience suggests that people with brain disorders can be oriented (and perform well on the Orientation-Log), but still exhibit significant cognitive limitations, such as with respect to memory functioning and executive skills. The Cog-Log assists in evaluating this group. Typically, the Orientation-Log is administered initially. The Cog-Log is added to or replaces the O-Log when orientation is achieved.

The Cog-Log is not intended to supplant other assessments of mental status, such as the Cognistat or Mini-Mental Status Examination. These assessments tend to be more lengthy and require some materials, so it is more difficult to use them at bedside. The Cog-Log is intended to be used during morning rounds repetitively, so that change in cognitive status can be easily documented. The Cog-Log is not intended to replace more extensive evaluations of cognitive skills, such as found in a neuropsychological evaluation. The latter provides a much better means of gauging the severity of deficits in specific areas (such as memory and concentration skills) and thus provides more information to guide rehabilitation efforts. As a general measure of cognitive status, the Cog-Log does not provide information about specific areas of cognitive ability except in very cursory fashion.
