Title: Health of Abraham Lincoln
Content:  Abraham Lincoln's health has been the subject of both contemporaneous commentary and subsequent hypotheses by historians and scholars. Until middle age, his health was fairly good for the time. He contracted malaria in 1830 and 1835; the latter was the worse of the two cases. He contracted smallpox in 1863 during an 1863 to 1864 epidemic in Washington, D.C. Throughout his life he experienced periods of depression, which could be genetic, due to life experiences or trauma, or both. Lincoln took blue mass pills, which contained mercury. Based on his behavior and physical condition while taking the pills and after he quit taking them, Lincoln may have suffered from mercury poisoning. It has been theorized that Lincoln had Marfan syndrome or, more likely, Multiple endocrine neoplasia type 2B, both rare genetic diseases.

Content: Malaria: Lincoln had malaria at least twice. The first was in 1830, along with the rest of his family. They had just arrived in Illinois that year. The second episode was in the summer of 1835, while living in New Salem. Lincoln was then so ill that he was sent to a neighbor's house to be medicated and cared for. ; Smallpox: November 18, 1863, while at the dedication of the Soldiers' National Cemetery, Lincoln was quite ill with smallpox. Long thought to have been only a mild case, recent work suggests it was a serious illness.  Although it did not debilitate Lincoln, the disease did significantly affect his White House routine, and limited the advisors with whom he could meet.  While caring for him, Lincoln's valet William H. Johnson contracted the disease and ultimately died in January 1864. Lincoln arranged and paid for Johnson to be buried at Arlington National Cemetery.

Content:   Lincoln is believed to have had depression, smallpox, and malaria. He took blue mass pills, which contained mercury, to treat constipation. It is unknown to what extent he may have suffered from mercury poisoning. Several claims have been made that Lincoln's health was declining before the assassination. These are often based on photographs of Lincoln appearing to show weight loss and muscle wasting. It is also suspected that he might have had a rare genetic disease such as Marfan syndrome or multiple endocrine neoplasia type 2B.

Content:  Several claims have been made that Lincoln's health was declining before the assassination. These are often based on photographs of Lincoln appearing to show weight loss and muscle wasting. The theories are that he suffered from multiple endocrine neoplasia type 2B (MEN2B) or Marfan syndrome, rare genetic disorders. DNA analysis of a pillowcase stained with Lincoln's blood, currently in possession of the Grand Army of the Republic Museum and Library in Philadelphia may be able to resolve open questions about Lincoln's health.

Content:  Based on Lincoln's unusual physical appearance, Dr. Abraham Gordon proposed in 1962 that Lincoln had Marfan syndrome. Testing Lincoln's DNA for Marfan syndrome was contemplated in the 1990s, but such a test was not performed. Lincoln's unremarkable cardiovascular history and his normal visual acuity have been the chief objections to the hypothesis, and today geneticists consider the diagnosis unlikely.
Title: Lincoln sign
Content:  The name Lincoln sign is based on a hypothetical diagnosis for a patient, namely the USA's 16th president Abraham Lincoln. In 1962, Dr Abraham M. Gordon suggested that Lincoln had Marfan's syndrome. In 1964, Dr Harold Schwartz adduced further evidence that Lincoln might have had Marfan syndrome. Later, Schwartz suggested that, based upon evidence shown in a famous photograph, Lincoln had the aortic insufficiency associated with what is now called Lincoln sign. However, Gordon's hypothesis is highly controversial.

Content:  In 2007, Dr. John Sotos proposed that Lincoln had multiple endocrine neoplasia type 2B (MEN2B). This hypothesis suggests Lincoln had all the major features of the disease: a marfanoid body shape, large, bumpy lips, constipation, hypotonia, a history compatible with cancer—to which Sotos ascribes the death of Lincoln's sons Eddie, Willie, and Tad, and probably his mother. The mole on Lincoln's right cheek, the asymmetry of his face, his large jaw, his drooping eyelid, and pseudodepression are also suggested as manifestations of MEN2B. MEN2B is a genetic disorder, and recently it has been demonstrated that Lincoln's biological mother, Nancy Lincoln, had many of the same unusual facial features as her son, as well as a marfanoid appearance. Lincoln's longevity is the principal challenge to the MEN2B hypothesis: Lincoln lived long enough to be assassinated at age 56. Untreated MEN2B is generally understood to result in death by the patient's mid-thirties, but there are several reported cases of MEN2B patients surviving into their 50s with no or little treatment. The hypothesis could be proven by DNA testing.

Content:  result of mercury poisoning, such as nerve damage that affected his gait. Shortly after his 1861 inauguration, Lincoln had a sudden and disquieting outburst of rage during a White House conversation. Finding that the blue mass pills made him "cross", Lincoln stopped taking them about August 1861 (5 months after his March inauguration). Then his anger greatly diminished, so much so that he rarely expressed anger and then only when it was situationally appropriate. "The remarkable thing about Lincoln's temper is not how often it erupted, buthow seldom it did, considering how frequently he encountered the insolence of epaulets, the abuse of friends and opponents alike, and the egomaniacal selfishness of editors, senators, representatives, governors, cabinet members, generals, and flocks of others who pestered him unmercifully about their own petty concerns."
Title: Health of Abraham Lincoln
Content:  Lincoln was contemporaneously described as suffering from melancholy, a condition which modern mental health professionals would characterize as clinical depression. Lincoln suffered depressed mood after major traumatic events, such as the death of Ann Rutledge in August 1835, the cessation of his (purported) engagement to Mary Todd Lincoln in January 1841 (after which several close associates feared Lincoln's suicide), and after the Second Battle of Bull Run. During his life Lincoln experienced the death of multiple close family members, including his mother, his sister, and two of his sons, Eddie and Willie. Mary Lincoln felt her husband to be too trusting, and his melancholy tended to strike at times he was betrayed or unsupported by those in whom he put faith. Whether he may have suffered from depression as a genetic predilection, as a reaction to multiple emotional traumas in his life, or a combination thereof is the subject of much current conjecture. Lincoln often combated his melancholic moods by delving into works of humor, likely a healthy coping mechanism for his depression.
