Method and system for predicting human cognitive performance using data from an actigraph

A method for utilizing information from an actigraph comprising:

• receiving data from the actigraph,
• selecting a function based on the data,
• calculating a cognitive performance capacity using the selected function,
• modulating the cognitive performance capacity with a time of day value, and
• providing the modulated value as the cognitive performance level.

A device for collecting data from at least one actigraph and providing a cognitive performance index for each of the at least one actigraph comprising:

• a receiver,
• a data analyzer connected to said receiver,
• a calculator connected to said receiver,
• a memory with modulation data,
• a modulator connected to said memory and said calculator, and
• at least one display connected to said modulator;
• and
• wherein said modulator provides a cognitive performance index for each of the at least one actigraph communicating with said device.

A device for collecting data from at least one actigraph and providing a cognitive performance index for each of the at least one actigraph comprising:

• means for receiving information from the at least one actigraph,
• means for selecting an evaluation function based on the received information for at least one of the at least one actigraph,
• means for calculating a value using the selected evaluation function for at least one of the at least one actigraph,
• means for storing modulation data,
• means for modulating the value with a corresponding piece of modulation data for at least one of the at least one actigraph, and
• means for displaying the modulated value for at least one of the at least one actigraph.

A device for predicting cognitive performance for an individual comprising:

• an actigraph,
• a sleep scorer connected to said actigraph,
• a data analyzer connected to said sleep scorer,
• a calculator connected to said analyzer,
• a memory with modulation data,
• a modulator connected to said memory and said calculator, and
• a display connected to said modulator.
