Overview
Lyme disease is divided into 3 stages and symptoms are stage specific. Symptoms include "bulls-eye" rash, with accompanying fever, malaise, and musculoskeletal pain (arthralgia or myalgia). It can progress to cardiovascular or neurological complications.
History
- The incubation period from infection to the onset of symptoms is usually 1–2 weeks, but can be much shorter (days), or much longer (months to years). Symptoms most often occur from May through September because the nymphal stage of the tick is responsible for most cases. [1]Asymptomatic infection exists, but is uncommon.[2]
- The specific areas of focus when obtaining the history, are outlined below:
- Tick bite
- Vacation,living, or working environment in endemic areas
- Spending time outdoor (especially in woody or grassy area).
Symptoms
Lyme disease is divided into 3 stages and symptoms are stage specific.
- Early localized disease
- Early disseminated disease
- Late disseminated disease
Early localized disease
Features of early localized disease includes erythema migrans and constitutional symptoms.
- Erythema migrans (EM) also known as Erythema chronicum migrans, "bull’s-eye" rash, or Lyme rash develops in around 70% - 80% of patients.[3]
- EM egins at the site of a tick bite after a delay of 3 to 30 days (average is about 7 days).
- EM gradually expands over a period of days reaching up to 12 inches(30 cm)or more across.
- EM may feel warm to touch but is rarely itchy or painful.
- EM clears as it enlarges, resulting in a target or “bull’s-eye” appearance.
- EM may appear on any area of the body but majority of times present in areas including axilla, inguinal region, popliteal fossa, or along belt line.
- Constitutional symptoms includes:[4]
Early disseminate disease
Features of early disseminated disease can be divided system wise and includes:
- Neurological symptoms:[5]
- Lymphocytic meningitis (most common neurological symptom)
- Cranial neuropathies(particularly facial nerve palsy)
- Painful radiculitis
- Mononeuritis multiplex[6]
- Pseudotumor cerebri
- Myelitis
- Chorea
- Cerebellar ataxia
- The triad of neurologic manifestation of Lyme disease includes meningitis, cranial neuritis, and radiculoneuritis.
Late disseminated disease
- Features of late disseminated disease can take months to years to manifest after the onset of infection.
- Lyme arthritis is dominant months later but chronic neurologic involvement becomes more obvious years later.
- The symptoms of late disseminated lyme disease includes:
- Neurological: These neurological symptoms may take months to years to manifest after the infection. They may sometimes manifest after a period of latency(as in neurosyphilis)[7]
- Sub-acute encephalopathy: Affects memory, mood, sleep, and sometimes with subtle language disturbances.
- Polyneuropathy
- Leukoencephalitis[8]
- Neurological: These neurological symptoms may take months to years to manifest after the infection. They may sometimes manifest after a period of latency(as in neurosyphilis)[7]
Common Symptoms
- The acute phase of Lyme disease infection is a characteristic reddish "bulls-eye" rash, with accompanying fever, malaise, and musculoskeletal pain (arthralgia or myalgia).
- The characteristic reddish "bull's-eye" rash (known as erythema chronicum migrans) may be seen in up to 80% of early stage Lyme disease patients,[9] appearing anywhere from one day to a month after a tick bite.[10]
- The rash does not represent an allergic reaction to the bite, but rather a skin infection with the Lyme bacteria, Borrelia burgdorferi sensu lato.
- An infection resulting from a B. mayonii infection may cause a diffuse rash, erupting in "red spots," spanning the entire body.
Less Common
- Cardiac manifestations (up to 10% of patients may have cardiac manifestations including heart block and palpitations[11])
- Neurologic symptoms (neuroborreliosis may occur in up to 18%), as well as simple altered mental status as the sole presenting symptom has been reported in early neuroborreliosis.[12]
Chronic Disease
- Untreated or persistent cases may progress to a chronic form most commonly characterized by meningoencephalitis
- Cardiac inflammation (myocarditis)
- Frank arthritis
- It should be noted, however, that chronic Lyme disease can have a multitude of symptoms affecting numerous physiological systems.
- The symptoms appear heterogeneous in the affected population, which may be due to innate immunity or variations in Borrelia bacteria.
- Late symptoms of Lyme disease can appear months or years after initial infection and often progress in cumulative fashion over time.
- Neuropsychiatric symptoms often develop much later in the disease progression, much like tertiary neurosyphilis.
Chronic neurological disorders
- In addition to the acute symptoms, chronic Lyme disease can be manifested by a wide-range of neurological disorders, either central or peripheral including:
- Neuropsychiatric disturbances can occur (possibly from a low-level encephalitis), which may lead to symptoms of memory loss, sleep disturbances, or changes in mood or affect.
- In rare cases, frank psychosis have been attributed to chronic Lyme disease effects, including misdiagnoses of schizophrenia and bipolar disorder.
- Panic attack and anxiety can occur, also delusional behavior, including somataform delusions, sometimes accompanied by a depersonalization or derealization syndrome similar to what was seen in the past in the prodromal or early stages of general paresis.[15]
Lyme Carditis
- Cardiac involvement occurs in about 5—10% of untreated Lyme disease and patients usually have symptoms related to fluctuating degrees of atrioventricular block (first-degree block to complete heart block) including lightheadedness, palpitations, shortness of breath, chest pain, and syncope.[16]
- Less commonly, patients may present with an acute picture of left ventricular dysfunction, cardiomegaly, perimyocarditis, or pancarditis without noticeable cardiac murmurs.[17]
- Lyme carditis can occur independently, it is usually accompanied by other cutaneous, joint, or neurologic features of Lyme disease.[18]
