Red light therapy is used for more than all that you listed. Many people claim it is also useful in Alzheimer's disease / dementia as well as for Parkinson's disease! It is also supposed to be helpful to improve sleep. These type of red lights are installed inside a helmet type device and are warn for specific amounts of time each use.
They're a bit more expensive than the handheld unit shown in your article though at about double the price and higher.
