Symptoms and Signs – Differential Diagnosis of Agitation
Agitation is a condition characterized by heightened arousal, elevated tension, and irritability, which can result in bewilderment, excessive activity, and open aggression. Agitation can arise due to toxic, metabolic, or viral factors, as well as brain injury or a psychiatric condition. Additionally, it can arise from discomfort, elevated body temperature, unease, substance consumption and cessation, heightened sensitivity responses, and diverse medical conditions. It can emerge gradually or abruptly and persist for a duration ranging from minutes to months. Agitation, regardless of its intensity, exacerbates with elevated body temperature, discomfort, psychological tension, or external triggers.
Agitation by itself just indicates a shift in the patient's state. Nevertheless, it serves as a valuable sign of an evolving illness. Acquiring a thorough history is crucial in identifying the root cause of agitation.
Historical and Physical Assessment
Evaluate the intensity of the patient's restlessness by observing the quantity and characteristics of agitation-related behaviors, such as emotional instability, disorientation, cognitive impairment, excessive activity, and aggression. Gather a comprehensive medical history from the patient or a family member, encompassing details on their dietary habits, documented allergies, and utilization of herbal remedies.
Inquire about the patient's current medical conditions or any ongoing treatments for disorders. Has he experienced any recent instances of infections, physical injuries, psychological strain, or alterations in his sleep patterns? Inquire with the patient regarding their utilization of prescribed medications, as well as any over-the-counter drugs, including vitamins and herbal remedies. Examine for indications of substance misuse, such as visible marks from needle injections and enlarged pupils. Inquire about the consumption of alcoholic beverages. Collect the patient's initial vital signs and neurologic condition as a reference for future comparison.
Differential Diagnosis of Anxiety
Alcohol withdrawal syndrome.
Alcohol withdrawal syndrome is characterized by a range of agitation, from mild to severe, as well as hyperactivity, tremors, and anxiety. Delirium, a dangerous phase of alcohol withdrawal, is characterized by intense restlessness along with hallucinations, sleeplessness, excessive sweating, and a low mood. As the withdrawal develops, the patient's pulse rate and temperature increase. This can lead to status epilepticus, cardiac fatigue, and shock.
Anxiety.
Anxiety elicits a range of agitation levels. The patient may exhibit a lack of awareness regarding his anxiousness or may express complaints about it without possessing knowledge of its underlying cause. Additional observations encompass symptoms such as nausea, vomiting, diarrhea, chilly and moist skin, frontal headache, back discomfort, sleeplessness, sadness, and tremors.
Dementia.
Various prevalent disorders, such as Alzheimer's and Huntington's illnesses, can lead to agitation ranging from mild to severe. The patient may exhibit a decline in memory, attention span, problem-solving capacity, and attentiveness. Additionally, hypoactivity, wandering behavior, hallucinations, aphasia, and sleeplessness may manifest.
Drug withdrawal syndrome. Drug withdrawal syndrome can cause varying degrees of agitation, ranging from mild to severe. Findings associated with the medicine differ, but can include anxiousness, stomach cramps, excessive sweating, and loss of appetite. During opioid or barbiturate withdrawal, individuals may experience a reduction in their level of consciousness (LOC), as well as seizures, and an increase in blood pressure, heart rate, and breathing rate.
Hepatic encephalopathy
Agitation is only seen in cases of fulminating encephalopathy. Additional observations consist of somnolence, unconsciousness, a distinctive odor known as fetor hepaticus, involuntary flapping of the hands (asterixis), and exaggerated reflexes (hyperreflexia).
Hypersensitivity reaction
The presence of moderate to severe agitation may indicate the onset of a reaction. Agitation might be followed by urticaria, pruritus, and swelling of the face and dependent areas, depending on the intensity of the reaction.
With anaphylactic shock, a potentially life-threatening reaction, agitation occurs rapidly along with apprehension, urticaria or diffuse erythema, warm and moist skin, paresthesia, pruritus, edema, dyspnea, wheezing, stridor, hypotension, and tachycardia. Additionally, one may experience abdominal pains, vomiting, and diarrhea.
Hypoxemia refers to a condition in which there is a deficiency of oxygen in the blood. Commencing with a state of restlessness, agitation swiftly escalates. The patient may experience cognitive disorientation and exhibit compromised decision-making abilities and physical control. In addition, he may experience headaches, rapid heart rate, rapid breathing, difficulty breathing, and bluish discoloration of the skin.
Elevated intracranial pressure (ICP)
It is typically accompanied with initial symptoms of restlessness, followed by subsequent manifestations of headache, nausea, and vomiting.Elevated intracranial pressure (ICP) leads to respiratory alterations, including Cheyne-Stokes, cluster, ataxic, or apneustic breathing patterns. It also causes slow, nonreactive, or unequal pupils, widening pulse pressure, increased heart rate, decreased level of consciousness (LOC), seizures, and movement abnormalities such as decerebrate or decorticate posturing.
Post-head trauma syndrome
Following the damage, whether it be a short time or several years later, the individual may experience varying degrees of agitation, which can range from mild to severe. This agitation is marked by symptoms such as confusion, difficulty focusing, sudden bursts of anger, and emotional instability. Additional observations encompass symptoms such as exhaustion, aimless conduct, and impaired decision-making.
Vitamin B6 deficiency
Agitation can vary in intensity, ranging from little to extreme. Additional consequences encompass convulsions, peripheral tingling sensations, and skin inflammation. There is also a possibility of experiencing oculogyric crises.
Other Causes
Drugs
Mild to moderate agitation, which is commonly dose related, develops as an adverse reaction to central nervous system stimulants — especially appetite suppressants, such as amphetamines and amphetamine- like drugs, and sympathomimetics, such as ephedrine, caffeine, and theophylline.
Radiographic contrast media.
Reaction to the contrast medium injected during various diagnostic tests produces moderate to severe agitation along with other signs of hypersensitivity.
Special Considerations
Because agitation can be an early sign of many different disorders, continue to monitor the patient’s vital signs and neurologic status while the cause is being determined. Eliminate stressors, which can increase agitation. Provide adequate lighting, maintain a calm environment, and allow the patient ample time to sleep. Ensure a balanced diet, and provide vitamin supplements and hydration.
Remain calm, nonjudgmental, and nonargumentative. Use restraints sparingly because they tend to increase agitation. If appropriate, prepare the patient for diagnostic tests, such as a computed tomography scan, skull X-rays, magnetic resonance imaging, and blood studies.
Patient Counseling
Reassure the patient, and orient him to the procedures and routines of the unit. Provide emotional support and a quiet environment. Explain stress reduction measures.
Pediatric Pointers
A common sign in children, agitation accompanies the expected childhood diseases as well as more severe disorders that can lead to brain damage: hyperbilirubinemia, phenylketonuria, vitamin A deficiency, hepatitis, frontal lobe syndrome, increased ICP, and lead poisoning. In neonates, agitation can stem from alcohol or drug withdrawal if the mother abused these substances.
When evaluating an agitated child, remember to use words that he can understand and to look for nonverbal clues. For instance, if you suspect that pain is causing agitation, ask him to tell you where it hurts, but make sure to watch for other indicators, such as wincing, crying, or moving away.
Geriatric Pointers
Any deviation from an older person’s usual activities or rituals may provoke anxiety or agitation. Any environmental change, such as a transfer to a nursing home or a visit from a stranger in the patient’s home, may trigger a need for treatment
