anxiety
"My husband is on a "light" dose of Neurontin (Gabepentin) and the medicine really works to relieve his anxiety.  He has Parkinson's Disease and mild cognitive disorder, as well as Parkinson's depression.  Neurontin works well on his tremor and his anxiety, but higher doses make him "foggy."  His dosage is 800mg spread over 12-16 hours, with the option to increase the dose to 1000mg per day, depending on his anxiety level.  He has been on Neurontin for many years and it continues to work well for him."
