7. Balance Problems: LOSA can affect spatial processing, leading to issues with balance and coordination.
8. Cognitive Decline: As LOSA progresses, individuals may experience cognitive decline, including problems with memory, attention, and executive function.
9. Mood Changes: Some individuals may experience mood disturbances, such as depression or anxiety, as a result of LOSA-related symptoms.
10. Behavioral Changes: LOSA can impact behavior, leading to irritability, agitation, or social withdrawal.
11. Fatigue: Chronic fatigue may occur as a result of cognitive and perceptual challenges associated with LOSA.
12. Headaches: Some individuals with LOSA may experience headaches, although the exact mechanism is not fully understood.
13. Difficulty Recognizing Faces: LOSA can affect the ability to recognize familiar faces, a condition known as prosopagnosia.
14. Impaired Object Manipulation: Individuals may have difficulty manipulating objects or judging their spatial relationships accurately.
15. Reduced Visual Acuity: LOSA may lead to decreased visual acuity, making it challenging to see details or fine patterns.
16. Sensory Processing Issues: LOSA can affect the brain’s ability to process sensory information, leading to heightened sensitivity or diminished perception.
17. Slowed Processing Speed: Cognitive processing may become slower as LOSA progresses, impacting reaction times and information processing.
18. Language Impairments: Some individuals may experience difficulties with language, including word-finding difficulties or trouble understanding spoken or written language.
19. Disorientation: LOSA can cause disorientation in time, place, or person, leading to confusion or agitation.
20. Changes in Gait: LOSA may affect walking patterns, leading to unsteady or shuffling gait.

Diagnostic Tests:

1. Medical History: A thorough medical history, including a review of symptoms and risk factors, can provide valuable information for diagnosing LOSA.
2. Physical Examination: A neurological examination can help assess cognitive function, visual perception, and coordination.
3. Neuroimaging: Imaging tests such as magnetic resonance imaging (MRI) or computed tomography (CT) scans can detect structural changes in the brain, including atrophy in the lateral occipital sulcus region.
4. Visual Field Testing: This assesses peripheral vision and can identify any visual field defects associated with LOSA.
5. Neuropsychological Testing: These tests evaluate cognitive function, including memory, attention, language, and executive function, which may be affected by LOSA.
6. Electroencephalogram (EEG): EEG measures electrical activity in the brain and may be used to assess brain function and detect abnormalities associated with LOSA.
7. Blood Tests: Blood tests can help rule out other potential causes of cognitive decline or neurological symptoms, such as vitamin deficiencies or metabolic disorders.
8. Genetic Testing: In cases where a genetic predisposition to neurodegenerative diseases is suspected, genetic testing may be performed to identify specific mutations.
9. Lumbar Puncture (Spinal Tap): This procedure involves collecting cerebrospinal fluid from the spinal canal and may be done to look for signs of infection or inflammation in the central nervous system.
10. Electroretinography (ERG): ERG measures the electrical response of the retina to light stimulation and may be used to assess visual function in individuals with LOSA.
