Frontal lobe function

Voluntary movement, intellect, orientation
Broca's Area (Left): speech, concentration
Personality, temper, judgement, reasoning, behavior, self-awareness, executive function


Frontal lobe impairment

Contralateral weakness
perseveration, inattention
Personality changes, antisocial behavior
Impaired concentration, apathy
Broca's aphasia (expressive deficits)
Delayed or poor initiation
Emotional lability


Parietal lobe function

Associated with sensation of touch, kinesthesia, perception of vibration, and temperature
Receives info from other areas of the brain regarding hearing, vision, motor, sensory, and memory
Provides meaning for objects
Interprets language and words
Spatial and visual perception


Parietal lobe impairments

Dominant hemisphere (typically left): agraphia, alexia, agnosia
Non-dominant hemisphere (typically right): dressing apraxia, constructional apraxia, anosognosia
Contralateral sensory deficits
Impaired language comprehension
Impaired taste


Temporal lobe function

Primary auditory processing and olfaction
Wernicke's area (left hemisphere): ability to understand and produce meaningful speech, verbal and general memory, assists with understanding language
The rear of the temporal lobe enables humans to interpret other people's emotions and reactions


Temporal lobe impairment

Learning deficits
Wernicke's aphasia (receptive deficits)
Antisocial, aggressive behaviors
Difficulty with facial recognition
Difficulty with memory, memory loss
Inability to categorize objects


Occipital lobe function

Main processing center for visual information
Processes visual information regarding colors, light, and shapes
Judgement of distance, seeing in three dimensions


Occipital lobe impairment

Homonymous hemianopsia
Impaired extraocular muscle movement and visual deficits
Impaired color recognition
Reading and writing impairment
Cortical blindness with bilateral lobe involvement


Meningitis signs and symptoms

Fever, headache, vomiting
Complaints of a stiff and painful neck, nuchal rigidity
Pain in the lumbar area and posterior thigh
Brudzinski's sign (flexion of the neck facilitates flexion of the hips and knees)
Kernig's sign (pain with hip flexion combined with knee extension)
Sensitivity to light


Signs of hydrocephalus or a blocked shunt include:

Enlarged head or bulging fontanelles in infants
Changes in vision
Large veins noted on scalp
Behavioral changes
Alteration in appetite, vomiting
"Sun setting" sign or downward deviation of the eyes
