A disease is never a mere loss or excess. There is always a reaction on the part of the organism or individual to restore, replace or compensate for and to preserve its identity, however strange the means may be.
Oliver SacksMusic can move us to the heights or depths of emotion. It can persuade us to buy something, or remind us of our first date. It can lift us out of depression when nothing else can. It can get us dancing to its beat. But the power of music goes much, much further. Indeed, music occupies more areas of our brain than language does-humans are a musical species.
Oliver SacksThe rhythm of music is very, very important for people with Parkinson's. But it's also very important with other sorts of patients, such as patients with Tourette's syndrome. Music helps them bring their impulses and tics under control. There is even a whole percussion orchestra made up exclusively of Tourette's patients.
