    individual's psychological functions
  • memory, attention, perception, problem solving
    and mental imagery

Patients With Cognitive Impairment
  • Brain Injuries
  • Dementia
  • Stroke
  • Multiple Sclerosis
  • ADHD

Impairments Relating to Brain Functions
  • Impairments Related to Perception
  • Difficulty understanding speech (receptive
  • This condition prevents the person from being
    able to understand words that are spoken
  • Impairments Related to Expression
  • Difficulty producing speech (expressive aphasia)
  • Changes in behavioral speech
  • reduced control of behavior to fit social norms

  • Impairments Related to Memory
  • Short term and long term memory deficits
  • Procedural memory lost can affect a persons
    ability to learn new manual tasks such as tying
  • Impairments Related to Processing
  • Poor executive functions time management,
    organization and judgment
  • Emotional and behavioral changes
  • Attention and staying on tasks capacity may be

AT for Impairments Related to Memory
  • Using multiple approaches to input can have a
    beneficial effect
  • It might help to provide documentation in more
    than one format--visual, auditory and tactile
  • Medication reminders, watch timers and telephone
    dialers all represent simple electronic
    accommodations that represent conveniences for
    the general population yet significant
    accommodations for those with memory deficits.

AT for Impairments Related to Processing
(Attention to detail, executive functioning,
visual auditory functioning, dementia)
  • The goal is to provide supports that can reduce
    disorganization and frustration
  • Computer-related accommodations include spell
    checker and grammar checker software
  • Using email for communication, rather than the
    telephone, can offer better understanding and
    documentation for later reference

AT for Dementia
  • Sensors
  • Floods - These detectors can be fitted on
    skirting boards or floors in the kitchen and
    bathroom. If the taps have been left running they
    shut off the water and raise the alarm. 
  • Falls - Sensors worn on the wrist can detect the
    impact of a person falling.
  • Gas - If someone forgets to turn the gas off,
    this device will automatically shut off the gas
    and raise the alarm.

  • Getting up in the night - A pressure mat
    sensor is placed by the bed and a sensor
    activates an alarm when the person gets up in the
    night, so that their carer can help them get to
    the toilet

Memory aids
  • Reminder messages
  • When a person enters or leaves their home, these
    gadgets activate a voice telling them to pick up
    their keys or lock the front door etc.
  • Clocks and calendars
  • Clocks that show whether it is evening or morning
    can help prevent disorientation, particularly in
    the dark winter months.
  • Medication aids

  • Locator devices
  • These devices can be attached with a keyring or
    Velcro to items that are often mislaid.
  • If a person wants to find a particular item, they
    press a colour-coded button on a radio
    transmitter and the device with the corresponding
    colour will beep until the item is picked up.
