There are several forms of dementia, some are more common than others, but all are disease significantly hindering daily life. It is progressive and lasts until the end of life.
Occipital lobe: vision, analysis of the color, motion, shape, depth;visual associations, assessment, decide whether the impression is analyzed and what its priority. Results occipital lobe damage:hole in the visual field (skotoma);difficulties in the placement of objects seen;visual hallucinations, inaccurate vision of objects, seeing halos;difficulties in identifying colors;difficulty in recognizing characters, symbols, words written;difficulties in identifying the drawings;difficulties in identifying the subject's movement;difficulty in reading and / or writing.
The temporal lobe:turn the top and lid: hearing music, phonemic and audio experience;Wernicke's area - speech comprehension, grammar, prosody;Lower curve: object recognition;categorization of objects, verbal memory, memorizing;The basal part: analysis of odors Damage to the temporal lobes:impaired hearing, speech understanding and perception of sounds;disorders of selective attention on visual and auditory stimuli;problems in recognizing seen objects, difficulty in recognizing faces (prosopagnosia);impairment of organizing and categorizing verbal information;the left hemisphere - the difficulty in understanding speech (Wernicke's aphasia);damage to the right hemisphere can cause verbiage;difficulties in describing objects seen;memory problems - anterograde amnesia, problems remembering;sexual behavior disorders;control disorders aggressive behavior
Parietal lobe :Upper part : the feeling of touch , temperature, pain ;location of sensory impressions ;right lower part : working memory associated with spatial orientation , imagination, reference system relative to its body constructed on the basis of visual sensations ;left side of the bottom : modeling spatial relationships finger movements , mental rotation , movement speed rating ;between and medial part : purposeful movements ;integration of motion and vision ;Sensory integration and vision in one percept ;manipulation of objects requiring coordination and imagination of space / mobility.understanding of the symbolic language , abstract concepts , geometric style. Parietal lobe damage :indivisibility total attention;inability of the eye to focus on a particular area ( visual apraxia ) ;difficulty in spatial orientation ;difficulties in integrating the visual together ( symultagnozja ) ;difficulties in coordinating eye and hand movement ;inability to purposeful action that requires movement ( apraxia ), problems in taking care of each other;left - the inability to distinguish directions, left-rightdifficulties in counting ( dyscalculia ) and mathematics , both algebra and geometry ;inability to name an object ( anomie ) ;around the left angular gyrus - inability to umiejscowanienia words written ( agraphia ) ;problems with reading;right - lack of awareness of certain areas of the body and SPACE ( unilateral neglect ) ;anozagnozja , denial of disability ;difficulties in drawing ;difficulties in constructing objects ;personality disorders (usually parietal...
