Spatial orientation (the inverse being spatial disorientation, aka spatial-D) is the ability to maintain body orientation and posture in relation to the surrounding environment (physical space) at rest and during motion. Humans have evolved to maintain spatial orientation on the ground.
The syndrome rarely presents itself the same way in every patient. Some symptoms that occur may be: [citation needed] Constructional apraxia: difficulty in constructing: drawing, copying, designs, copying 3D models; Topographical disorientation: difficulty finding one's way in the environment; Optic ataxia: deficit in visually-guided reaching
Topographical disorientation is the inability to orient oneself in one's surroundings, sometimes as a result of focal brain damage. [1] This disability may result from the inability to make use of selective spatial information (e.g., environmental landmarks) or to orient by means of specific cognitive strategies such as the ability to form a mental representation of the environment, also known ...
Problems with balance can occur when there is a disruption in any of the vestibular, visual, or proprioceptive systems. Abnormalities in balance function may indicate a wide range of pathologies from causes like inner ear disorders, low blood pressure, brain tumors, and brain injury including stroke.
This causes unpleasant disorientation sensations often quite distinct from terrestrial motion sickness, but with similar symptoms. The symptoms may be more intense because a condition caused by prolonged weightlessness is usually quite unfamiliar. [citation needed]
Symptoms of sleep inertia include: Grogginess. Drowsiness. Disorientation or confusion. Impaired cognitive function (trouble focusing, slower reaction times, and lowered spatial awareness)
Dizziness is an imprecise term that can refer to a sense of disorientation in space, vertigo, or lightheadedness. [1] It can also refer to disequilibrium [2] or a non-specific feeling, such as giddiness or foolishness. [3] Dizziness is a common medical complaint, affecting 20–30% of persons. [4]
Spatial anxiety (sometimes also referred to as spatial orientation discomfort [1]) is a sense of anxiety an individual experiences while processing environmental information contained in one's geographical space (in the sense of Montello's classification of space), [2] with the purpose of navigation and orientation through that space (usually unfamiliar, or very little known).
