I found it interesting that the article mentions amantadine. I suffered a mild traumatic brain injury with post-concussion syndrome whose effects were persisting for quite a long time. While vestibular therapy made a big difference, once that treatment plateaued I started taking amantadine -- it had been suggested by my doctor before, but I'm a stubborn person. The difference that amantadine made in terms of my concussion was significant.<p>My migraines almost completely vanished, but more importantly I had the cognitive energy to do things that had been impossible for many months, such as programming and playing my musical instruments. I had to take it slow at first, but the difference amantadine made was truly remarkable.<p>It's not fully understood how this drug works, especially considering that it was originally used as an anti-flu medicine. Furthermore, my understanding is that it was no longer used in treating Parkinsons. But it's one of the few drugs that seems to have an effect in people suffering from post-concussion syndrome. A cousin of mine who also suffered from pretty serious post-concussion syndrome likewise had good results with amantadine.<p>It should be noted that the use of amantadine is controversial in concussion treatment. From what I've heard, some patients don't get much benefit, and the effects tend to wear off over time. Also, it caused me to have problems with insomnia, which were mostly addressed through sleep hygiene and melatonin. But I thought that I'd share my experience here, as this experience helped me to understand just how physical our mind is, and how there are likely a variety of avenues for helping the brain when it is damaged.
