The brain is very complex, and is composed of many different areas and types of tissue, or matter. The different functions of different tissues in the brain may be more or less susceptible to age-induced changes. The brain matter can be broadly classified as either grey matter, or white matter. Grey matter consists of cell bodies in the cortex and subcortical nuclei, whereas white matter consists of tightly packed myelinated axons connecting the neurons of the cerebral cortex to each other and with the periphery. Loss of neural circuits and brain plasticity
Brain plasticity refers to the brains ability to change structure and function. This ties into the common phrase, "if you dont use it, you lose it," which is another way of saying, if you dont use it, your brain will devote less somatotopic space for it. One proposed mechanism for the observed age-related plasticity deficits in animals is the result of age-induced alterations in calcium regulation. The changes in our abilities to handle calcium will ultimately influence neuronal firing and the ability to propagate action potentials, which in turn would affect the ability of the brain to alter its structure or function (i.e. its plastic nature). Due to the complexity of the brain, with all of its structures and functions, it is logical to assume that some areas would be more vulnerable to aging than others. Two circuits worth mentioning here are the hippocampal and neocortical circuits.
Surgical therapies include:

Distal and proximal osteotomies of the 5th metatarsal can be used to correct the intermetatarsal and metatarsophalangeal angle causing the TB. Diagnosis
Tailors bunion is easily diagnosed because the protrusion is visually apparent. X-rays may be ordered to help the surgeon find out the severity of the deformity. Types of Tailors bunions
Type 1: The head of the 5th metatarsal is thickened and enlarged. Type 2: A 5th metatarsal with an increased lateral curve and a normal fourth and fifth inter-metatarsal angle. Type 3: Has the greatest lateral angular disposition of the 5th metatarsal compared to the 4th metatarsal, this phenomenon increases the 4th and 5th inter-metatarsal angles. This is generally the most symptomatic type of Tailors bunion. Type 4: A combination of at least two types of bunionettes (TB). Lesser toe deformities leading to falls
Five studies examined associations between falls and foot disorders. Significant associations were found between falls and plantar fasciitis, corns or bunions and lesser toe deformity (such as Tailors bunions). The results of these studies show that "Older people who fell were more likely to have foot pain, hallux valgus, and lesser toe deformity". See also
