What is Parkinsons Disease?

• PD is a neurological disorder that affects the
  nerve cells to inhibit motor movements.
• PD causes the level of Dopamine to drop between
  the nerve cells.

Notice the size difference. Also, the red places
in the brain are where Dopamine is stored
3
What is Dopamine?

• Dopamine is a chemical transmitter that allows
  nerve cells to transmit signals to the next nerve
  cells.
• A drop of Dopamine means a drop in ability to
  communicate between the nerve endings and the
  next nerve cells dendrites.

Dopamine Continued

• The effects of less Dopamine results in a fault
  of communications resulting in a lack or awkward
  motion of body parts.
• PD affects part of the brain called the
  Substantia Nigra which controls the voluntary
  movements in the human body while also produces
  Dopamine

5
Symptoms

• The first noticeable effects of PD is a tremor in
  a small part of the body, usually solely the hand
  on one side of the body.
• Unfortunately, overtime, the symptoms will worsen
  and other changes will be noticed.

6
Symptoms

• Other effects of PD may include
• Sleep Loss
• Speech Difficulties
• Depression
• Postural Difficulties
• Unpredictable loss of motor movements
• Rigidity

7
Progressive Supranuclear Palsy

• The result of PD affecting the part of the brain
  called the Atrophied Tectum
• This results in the symptoms of Postural
  Difficulties and as well as trouble with
  eyesight, eye movement, breathing, and swallowing

8
Treatment

• PD is usually treated with L-Dopa which changes
  to Dopamine to add more of these chemical
  transmitters in circumstances of a lack of
  Dopamine in damaged nerve cells.
• There are other ways of treating tremors in parts
  of the body by using microchips to eliminate the
  unnecessary electrical impulses
