Brief Summary

The purpose of this study is to explore the efficacy of the drug Amantadine for the treatment of freezing of gait in patients with Parkinson's Disease. The investigators hypothesize that amantadine is useful for management of freezing of gait in subjects with Parkinson's Disease.

Outcome Measures

Primary Outcomes (2)

  • Timed Up and Go (TUG) - ON Usual Medication

    This is a walking assessment. The subject will begin in the seated position, stand up, walk 7 meters, turn around, and sit back down. The entire process from leaving the chair to returning to the chair will be timed. Also, the Timed Up and Go (TUG) will be done both in the ON and OFF states.

    Baseline, change at 4 weeks

  • Timed Up and Go (TUG) - OFF Usual Medication

    This is a walking assessment. The subject will begin in the seated position, stand up, walk 7 meters, turn around, and sit back down. The entire process from leaving the chair to returning to the chair will be timed. Also, the Timed Up and Go (TUG) will be done both in the ON and OFF states.

    Baseline, change at 4 weeks

Secondary Outcomes (9)

  • Modified Timed Up and Go (mTUG)

    Baseline, change in 4 weeks

  • Analysis of Motor Functioning Using the Parkinson's Home Diaries

    Baseline, change in 4 weeks

  • Freezing of Gait Questionnaire

    Baseline, change in 4 weeks

  • Clinical Global Impression (CGI)

    4 weeks

  • Parkinson's Disease Questionnaire-39 (PDQ-39)

    Baseline, week 4

  • +4 more secondary outcomes

  • H\&Y stage 2.5-3
  • Presence of freezing of gait (FOG) as determined by UPDRS Part I score \> 2
  • Ability to walk for 2 minutes in the ON and OFF state
  • Stable regimen of PD medications for 30 days prior to screening
  • Ability to comply with the study procedures
  • If female, be either post menopausal for at least 2 years, surgically sterilized or have undergone hysterectomy or, if of child bearing potential they must be willing to avoid pregnancy by using an adequate method of contraception as defined in Section 6.4.10 for four weeks prior to, during and four weeks after the last dose of trial medication. For the purposes of this trial, women of childbearing potential are defined as all female subjects after puberty unless they are post-menopausal for at least two years, are surgically sterile or are sexually inactive.
  • Willing and able to provide informed consent.

You may not qualify if:

  • Presence of other co morbid conditions that can contribute to gait dysfunction (orthopedic, rheumatologic, cardiac, other)
  • Presence of freezing of gait (FOG) ONLY in medications ON state
  • Presence of freezing of gait (FOG) ONLY in medications OFF state
  • Presence of significant cognitive dysfunction as determined by Montreal Cognitive Assessment (MoCA) \<20
  • Presence of clinically significant depression as determined by geriatric depression scale (GDS)- 15\>5
  • Presence of clinically significant hallucinations
  • Inability to sign informed consent
  • Participation in the physical therapy aimed at management of PD for the duration of the study (PT for orthopedic issues will be allowed)
  • Contraindications for use of Amantadine ( prior history of allergic reaction, history of known renal insufficiency with Cr \> 2)
  • If female, be pregnant or lactating
