# Bradykenisia: Bradykenisia is a slowing of voluntary movement. Parkinson's sufferers with Bradykenisia often have incompleteness of movement, difficulty in initiating movement and arrests of ongoing movement. Parkinson's disease may cause a slow, unsteady walk and bad posture. Certain muscles may freeze up making any movement difficult. Even digestive systems and swallowing can slow down as a result of bradykenisia. The slowness of movement may also affect facial muscles.

# Rigidity of Muscles: Muscles often become stiff and inflexible. Normally after muscle contraction a muscle will relax. For Parkinsons disease sufferers the muscle tone of an affected limb is stiff. Rigidity often results in a decreased range of motion. It may also cause pain and cramps at the muscle site.

# Postural Instability: Most Parkinson's disease sufferers find it difficult to stand up straight. They also find it difficult to stay standing in one position for prolonged amounts of time. They are also more susceptible to falls as a result of postural instability.

# Loss of Automatic Movement: Many unconscious acts like blinking, smiling and swinging arms when walking are lost by Parkinson's disease sufferers. Often they develop a fixed staring expression and appear to have no facial expression. They may also appear to be drooling as they no longer automatically swallow.

# Impaired Speech: Parkinson's disease sufferers often have problems speaking. Their voices are often monotonous and hard to hear.

# Micographia: Often individuals with Parkinson's disease have very small writing as a result of difficulty with fine motor movements.

# Dementia, Confusion and Anxiety: Secondary symptoms, Parkinson's disease suffers are often anxious and confused.  These are some of the most damaging symptoms. 

# Loss of Energy and Memory: Two of the most disabling symptoms of Parkinson's disease are the loss of energy and memory. Parkinsons sufferers are often very tired, but have difficulty sleeping. They also show signs of memory loss.
