Akinetic mutism secondary to subarachnoid hemorrhage
Diminution of basal ganglia dopaminergic function may play an important role in the generation of
akinetic mutism in a patient with anterior cerebral arterial infarct.
The model enables realistic beat-to-beat ventricular blood flow and pressure tracings that facilitate the understanding of the effects of
akinetic or dyskinetic aneurysms of various sizes on ventricular function and correctly predicts the effect of systolic dysfunction or decreased an-eurysmal distensibility on ventricular hemodinamics.
The emergence of motor impairment (gait abnormality), change in consciousness level (mental dullness and
akinetic mutism), and the episode of seizure showed the clinical picture of encephalopathy, which initiated further investigations.
For instance, the IIT says that the presence and extent of consciousness can be determined, in principle, also in cases in which we have no verbal report, such as infants or animals, or in neurological conditions such as minimally conscious states,
akinetic mutism, psychomotor seizures, and sleepwalking.
Over a long period of time, the structure of coherent EEG connections has been studied in our laboratory as the basis for research into the systemic organization of the human brain in conditions of coma and borderline post-comatose unconscious states (apallic syndrome or vegetative states,
akinetic mutism, etc.
Regional wall motion was characterized as normal, hypokinetic, or
akinetic.
She was pulled from the water but had been in a condition known as
akinetic mutism until her death.
She has been in a state of
akinetic mutism for 19 years, after nearly drowning at the age of three.
In terms of clinical features, 11 patients had tardive dyskinesia (including 5 with respiratory dyskinesia), 2 had akathisia, 19 had tremor (17 with resting tremor and 6 with asymmetric tremor, alone or in combination), and 3 had
akinetic rigidity.
Echocardiography demonstrated a large anteroapical infarct noted by
akinetic anteroseptal and anterior walls as well as a dyskinetic apex.
