Damage in the watershed region does not directly harm the areas of the brain involved in language production or comprehension; instead, the damage isolates these areas from the rest of the brain. [1] If there is damage to the frontal lobe, executive functions related to language use are often affected.
Transcortical sensory aphasia is characterized as a fluent aphasia. Fluency is determined by direct qualitative observation of the patient’s speech to determine the length of spoken phrases, and is usually characterized by a normal or rapid rate; normal phrase length, rhythm, melody, and articulatory agility; and normal or paragrammatic speech.

Central serous chorioretinopathy (CSC or CSCR), also known as central serous retinopathy (CSR), is an eye disease that causes visual impairment, often temporary, usually in one eye. [ 1 ] [ 2 ] When the disorder is active it is characterized by leakage of fluid under the retina that has a propensity to accumulate under the central macula.
Ocular hypertension is the presence of elevated fluid pressure inside the eye (intraocular pressure), usually with no optic nerve damage or visual field loss. [1] [2]For most individuals, the normal range of intraocular pressure is between 10 mmHg and 21 mmHg. [3]
Two significant causes of vision loss due to sensory failures include media opacity and optic nerve diseases, although hypoxia and retinal disease can also lead to blindness. Most causes of vision loss can cause varying degrees of damage, from total blindness to a negligible effect. Media opacity occurs in the presence of opacities in the eye ...
These mechanisms can be broken down into four major groups: speech generation (talking), speech comprehension (hearing), writing generation (writing), and writing comprehension (reading). In a practical sense, linguistic intelligence is the extent to which an individual can use language , both written and verbal, to achieve goals.
Long-term contact lens use can lead to alterations in corneal thickness, stromal thickness, curvature, corneal sensitivity, cell density, and epithelial oxygen uptake. . Other structural changes may include the formation of epithelial vacuoles and microcysts (containing cellular debris), corneal neovascularization, as well as the emergence of polymegethism in the corneal endoth
Global aphasia is a severe form of nonfluent aphasia, caused by damage to the left side of the brain, that affects [1] receptive and expressive language skills (needed for both written and oral language) as well as auditory and visual comprehension. [2]
