Light therapy apparatuses are configured to expose a subject to light that is tailored to address and/or diagnose at least one motor-related neurological condition. Blue-green light and green light are useful for treating motor-related neurological conditions or their symptoms. Deep red light and near infrared radiation may facilitate the repair of retinal cells and/or neurons that may be responsible for motor-related neurological conditions. Amber, orange and red light enable the early diagnosis of motor-related neurological conditions.
