Alternatively, some practitioners prefer "elevation". Elevation can help identify a melanoma, but lack of elevation does not mean that the lesion is not a melanoma. Most melanomas in the US are detected before they become elevated. By the time elevation is visible, they may have progressed to the more dangerous invasive stage.In-person inspection of suspicious skin lesions is more accurate than visual inspection of images of suspicious skin lesions. When used by trained specialists, dermoscopy is more helpful to identify malignant lesions than use of the naked eye alone. Reflectance confocal microscopy may have better sensitivity and specificity than dermoscopy in diagnosing cutaneous melanoma but more studies are needed to confirm this result. Ugly duckling
One method is the "ugly duckling sign". Correlation of common lesion characteristics is made. Lesions that deviate from the common characteristics are labeled an "ugly duckling", and a further professional exam is required. The "Little Red Riding Hood" sign suggests that individuals with fair skin and light-colored hair might have difficult-to-diagnose amelanotic melanomas. Extra care is required when examining such individuals, as they might have multiple melanomas and severely dysplastic nevi. A dermatoscope must be used to detect "ugly ducklings", as many melanomas in these individuals resemble nonmelanomas or are considered to be "wolves in sheeps clothing". These fair-skinned individuals often have lightly pigmented or amelanotic melanomas that do not present easy-to-observe color changes and variations. Their borders are often indistinct, complicating visual identification without a dermatoscope.
Acute aphasias
Expressive aphasia also known as Brocas aphasia, expressive aphasia is a non-fluent aphasia that is characterized by damage to the frontal lobe region of the brain. A person with expressive aphasia usually speaks in short sentences that make sense but take great effort to produce. Also, a person with expressive aphasia understands another persons speech but has trouble responding quickly. Receptive aphasia also known as Wernickes aphasia, receptive aphasia is a fluent aphasia that is categorized by damage to the temporal lobe region of the brain. A person with receptive aphasia usually speaks in long sentences that have no meaning or content. People with this type of aphasia often have trouble understanding others speech and generally do not realize that they are not making any sense. Conduction aphasia

Learning disability

Speech disorders
cluttering - a syndrome characterized by a speech delivery rate which is either abnormally fast, irregular, or both. dysarthria - a condition that occurs when problems with the muscles that helps a person to talk make it difficult to pronounce words. esophageal voice - involves the patient injecting or swallowing air into the esophagus. Usually learnt and used by patients who cannot use their larynges to speak. Once the patient has forced the air into their esophagus, the air vibrates a muscle and creates esophageal voice.
