Difficulty paying attention Difficulty concentrating Slowness of thinking Difficulty multi-tasking or task switching

Non-motor symptoms: thinking and memory

slide-3
SLIDE 3

Dopamine neurons (brain cells) in the substania nigra Biggest impact

  • n the putamen

Healthy Parkinson’s disease

slide-4
SLIDE 4

Habits are good! Habits allow you to automate behaviour and multi-task Habits depend on the putamen Do people with PD have trouble learning habits?

How do you measure habits?

  • Habitual actions are

automated

  • Goal-directed actions

require thinking about consequences

Next steps

  • Determine whether

humans have trouble developing habits

  • Determine if current

medications help restore habits (e.g., L-dopa)

  • Chemogenetics
slide-23
SLIDE 23

chemogenetics

  • Insert receptors into brain cells
  • Receptors are responsive to a

special chemical

  • Consume chemical in a tablet
  • Activate the putamen

Summa mmary

Repeated actions lead to habits No habits without dopamine Can chemo- genetics restore habits?
