Osteopenia, known as " low bone mass " or " low bone density ", is a condition in which bone mineral density is low. [ 1] Because their bones are weaker, people with osteopenia may have a higher risk of fractures, and some people may go on to develop osteoporosis. [ 2] In 2010, 43 million older adults in the US had osteopenia. [ 3]
Occipital neuralgia. Occipital neuralgia (ON) is a painful condition affecting the posterior head in the distributions of the greater occipital nerve (GON), lesser occipital nerve (LON), third occipital nerve (TON), or a combination of the three. It is paroxysmal, lasting from seconds to minutes, and often consists of lancinating pain that ...
Although astigmatism may be asymptomatic, higher degrees of astigmatism may cause symptoms such as blurred vision, double vision, squinting, eye strain, fatigue, or headaches. [7] Some research has pointed to the link between astigmatism and higher prevalence of migraine headaches. [8]
The symptoms and signs associated with convergence insufficiency are related to prolonged, visually demanding, near-centered tasks. They may include, but are not limited to, diplopia (double vision), asthenopia (eye strain), transient blurred vision, difficulty sustaining near-visual function, abnormal fatigue, headache, and abnormal postural adaptation, among others.
Scintillating scotoma is a common visual aura that was first described by 19th-century physician Hubert Airy (1838–1903). Originating from the brain, it may precede a migraine headache, but can also occur acephalgically (without headache), also known as visual migraine or migraine aura. [ 4]
Atypical trigeminal neuralgia ( ATN ), or type 2 trigeminal neuralgia, is a form of trigeminal neuralgia, a disorder of the fifth cranial nerve. This form of nerve pain is difficult to diagnose, as it is rare and the symptoms overlap with several other disorders. [ 1] The symptoms can occur in addition to having migraine headache, or can be ...
15% (50 year olds), 70% (over 80 year olds) [ 7] Osteoporosis is a systemic skeletal disorder characterized by low bone mass, micro-architectural deterioration of bone tissue leading to more porous bone, and consequent increase in fracture risk. It is the most common reason for a broken bone among the elderly. [ 3]
A concussion is a mild form of traumatic brain injury, or TBI. It occurs when the skull and brain are rapidly jolted back and forth. This is usually the result of a bump, bang, or blow to the head ...
